Question

The coordinates of a right triangle are A (5,-1), B (5,-6), and C (1,-6). If that triangle is reflected over the y-axsis, what are the coordinates of the reflected triangle?
The coordinate A becomes (?)
The coordinate B becomes (?)
The coordinate C becomes (?)

Answer 1

To reflect a point over the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

Given the coordinates of the triangle:
- A (5, -1)
- B (5, -6)
- C (1, -6)

Now we reflect each point over the y-axis:

1. **A (5, -1)**:
- The reflected point A' will be (-5, -1).

2. **B (5, -6)**:
- The reflected point B' will be (-5, -6).

3. **C (1, -6)**:
- The reflected point C' will be (-1, -6).

So the coordinates of the reflected triangle are:
- A' becomes (-5, -1)
- B' becomes (-5, -6)
- C' becomes (-1, -6)
