Hey guys! Today, let's dive into a fun geometry problem involving the rotation of a quadrilateral. We're given quadrilateral TUVW with vertices at T(-6, -2), U(-3, -3), V(-4, -6), and W(-7, -5). Our mission, should we choose to accept it, is to rotate this quadrilateral 270 degrees counterclockwise around the origin. Buckle up, because we're about to embark on a mathematical adventure!

Understanding Rotations in the Coordinate Plane

Before we jump into the specifics of our problem, let's quickly review the basics of rotations in the coordinate plane. A rotation is a transformation that turns a figure about a fixed point, which we'll assume is the origin (0, 0) unless otherwise specified. The amount of rotation is measured in degrees, and the direction can be either clockwise or counterclockwise. In our case, we're dealing with a 270-degree counterclockwise rotation.

The key to performing rotations is understanding how the coordinates of a point change after the rotation. For a 270-degree counterclockwise rotation, the transformation rule is (x, y) → (y, -x). This means that the x-coordinate of the original point becomes the y-coordinate of the rotated point, and the y-coordinate of the original point becomes the negative of the x-coordinate of the rotated point. This rule is super important, so let's keep it in mind as we work through our problem.

To really understand this, think about what's happening geometrically. A 270-degree counterclockwise rotation is the same as a 90-degree clockwise rotation. Visualizing this can help you remember the transformation rule. When you rotate a point 90 degrees clockwise, you're essentially swapping the x and y coordinates and changing the sign of the new x-coordinate. This is precisely what the (x, y) → (y, -x) rule does. Remember, visualizing rotations is key to truly grasping the concept, so try sketching out a few examples to solidify your understanding.

Understanding the transformation rule (x, y) → (y, -x) is crucial for accurately rotating points. Let's break down why this rule works. Imagine a point in the coordinate plane. When you rotate it 270 degrees counterclockwise, you're essentially moving it three-quarters of the way around a circle centered at the origin. This movement affects both the x and y coordinates. The original x-coordinate influences the new y-coordinate, and the original y-coordinate, with a sign change, influences the new x-coordinate. This swap and sign change are precisely captured by the transformation rule. So, remember this rule; it's your best friend when dealing with 270-degree rotations!

Now, let's take this understanding and apply it to our quadrilateral TUVW. We'll go through each vertex one by one, applying the transformation rule and finding the coordinates of the rotated vertices. This step-by-step approach will ensure we don't make any mistakes and that we accurately map the original quadrilateral onto its rotated image. This careful, methodical approach is a valuable strategy for solving any geometry problem, so let's get started!

Applying the Rotation Rule to Quadrilateral TUVW

Alright, let's get down to business and apply the rotation rule (x, y) → (y, -x) to each vertex of quadrilateral TUVW. We'll take it one vertex at a time to keep things organized and avoid any confusion. Remember, our vertices are T(-6, -2), U(-3, -3), V(-4, -6), and W(-7, -5).

  • Vertex T(-6, -2): Applying the rule, we swap the coordinates and negate the new x-coordinate. So, T' becomes (-2, -(-6)), which simplifies to T'(-2, 6).
  • Vertex U(-3, -3): Again, we swap and negate. U' becomes (-3, -(-3)), which simplifies to U'(-3, 3).
  • Vertex V(-4, -6): Let's do it again! V' becomes (-6, -(-4)), which simplifies to V'(-6, 4).
  • Vertex W(-7, -5): One last time! W' becomes (-5, -(-7)), which simplifies to W'(-5, 7).

So, after applying the 270-degree counterclockwise rotation, we have the new vertices: T'(-2, 6), U'(-3, 3), V'(-6, 4), and W'(-5, 7). These are the coordinates of the rotated quadrilateral. We've successfully transformed the original quadrilateral into its rotated image using the given transformation rule. It's like we've given our quadrilateral a mathematical spin!

To ensure our results are accurate, it's always a good idea to double-check our work. We can do this by visualizing the rotation. Imagine the original quadrilateral and then picture it rotating 270 degrees counterclockwise. Do the new coordinates we calculated make sense in terms of the rotated position? Another way to check is to plot both the original and rotated quadrilaterals on a coordinate plane. This visual representation can help you confirm that the rotation was performed correctly. Remember, double-checking your work is a crucial step in any mathematical problem-solving process. It helps you catch any potential errors and ensures that your final answer is accurate.

Let's summarize what we've done so far. We started with a quadrilateral TUVW and applied a 270-degree counterclockwise rotation using the transformation rule (x, y) → (y, -x). We carefully applied this rule to each vertex, swapping the coordinates and negating the new x-coordinate. This process gave us the new vertices of the rotated quadrilateral: T'(-2, 6), U'(-3, 3), V'(-6, 4), and W'(-5, 7). Now that we have these coordinates, let's move on to the final step: presenting our results clearly and concisely.

Presenting the Rotated Vertices

Now that we've calculated the coordinates of the rotated vertices, let's present our results in a clear and organized manner. This is super important for communicating our solution effectively. We want to make sure anyone looking at our work can easily understand what we've done and what the final answer is.

We can present the rotated vertices as follows:

  • T'(-2, 6)
  • U'(-3, 3)
  • V'(-6, 4)
  • W'(-5, 7)

This list clearly shows the coordinates of each rotated vertex. We can also write this in a more concise form, like this: T'(-2, 6), U'(-3, 3), V'(-6, 4), W'(-5, 7). Both ways are perfectly acceptable; the key is to be clear and easy to understand. Another great way to present the results is in a table format. A table can be especially helpful if you have a lot of data or multiple transformations to track. It provides a structured and organized way to display the original and transformed coordinates.

Vertex Original Coordinates Rotated Coordinates
T (-6, -2) (-2, 6)
U (-3, -3) (-3, 3)
V (-4, -6) (-6, 4)
W (-7, -5) (-5, 7)

This table provides a clear side-by-side comparison of the original and rotated vertices, making it easy to see the transformation that occurred. No matter which method you choose, the goal is to communicate your solution effectively. Clear communication is a vital skill in mathematics, as it allows others to understand your reasoning and appreciate your results. So, always take the time to present your work in a way that is easy to follow and understand.

Furthermore, consider adding a brief explanation of what you did to arrive at these coordinates. This adds context and demonstrates your understanding of the process. For example, you could say, "After applying a 270-degree counterclockwise rotation using the rule (x, y) → (y, -x), the new coordinates of the vertices are as follows..." This simple sentence provides a clear introduction to your results and reinforces the transformation you performed. Remember, the more clearly you communicate your solution, the more confident others will be in your answer.

Conclusion: Mastering Rotations

And there you have it, guys! We've successfully rotated quadrilateral TUVW 270 degrees counterclockwise. We started by understanding the transformation rule (x, y) → (y, -x), then we applied it to each vertex of the quadrilateral, and finally, we presented our results clearly and concisely. This problem demonstrates the power of transformations in geometry and how understanding the rules can help us manipulate shapes in the coordinate plane.
