Question

Describe fully the single transformation that maps triangle A onto triangle B

Answer 1

Reflection over the x-axis

Explanation:

Answer 2

Reflection over the x-axis

Explanation:

To get from Triangle A to Triangle B, Triangle A must be reflected over the x-axis. On Triangle A, the left-most point is at (1, -2). The corresponding point on Triangle B is at (1, 2). The rule for reflecting over the x-axis is (x, y) -> (x, -y). So, (1, -2) -> (1, 2).

I hope this helps :))
