Math Problem Statement

The triangle is reflected across the y-axis, and then reflected across the x-axis. What are the coordinates of the image of point C after the transformations?

Solution

Let's analyze the transformation step-by-step based on the graph and the instructions.

We are asked to reflect the triangle (and specifically point C) across the y-axis, followed by a reflection across the x-axis.

  1. Original coordinates of point C: From the graph, point C is located at (2,0)(2, 0).

Step 1: Reflect across the y-axis

  • When reflecting across the y-axis, we negate the x-coordinate while keeping the y-coordinate unchanged.
    • Reflection of (2,0)(2, 0) across the y-axis:
      (2,0)(-2, 0)

Step 2: Reflect across the x-axis

  • After reflecting across the y-axis, we now reflect across the x-axis, which negates the y-coordinate while keeping the x-coordinate unchanged.
    • Reflection of (2,0)(-2, 0) across the x-axis:
      (2,0)(-2, 0)

Thus, the coordinates of the image of point C after both transformations are (2,0)(-2, 0).

Would you like more details on these transformations?

Here are 5 related questions to consider:

  1. What happens to points located on the axes during reflections?
  2. How would the reflection process differ if point C had been located in a different quadrant?
  3. Can you generalize how coordinates change when reflecting across both the x- and y-axes?
  4. What is the result if we reflect the triangle first across the x-axis, then across the y-axis?
  5. What other transformations could you apply to change the position of point C?

Tip: Visualizing transformations on a graph can help solidify your understanding of how reflections work.
