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.
- Original coordinates of point C: From the graph, point C is located at .
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 across the y-axis:
- Reflection of across the y-axis:
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 across the x-axis:
- Reflection of across the x-axis:
Thus, the coordinates of the image of point C after both transformations are .
Would you like more details on these transformations?
Here are 5 related questions to consider:
- What happens to points located on the axes during reflections?
- How would the reflection process differ if point C had been located in a different quadrant?
- Can you generalize how coordinates change when reflecting across both the x- and y-axes?
- What is the result if we reflect the triangle first across the x-axis, then across the y-axis?
- 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.
