Question

PLEASE HELP!!!!

What isometric transformation was applied to triangle ABC?

1) Translation

2) reflection

3) dialation

4) rotation

Answer 1

The answer is option 2. It was a reflection over the line y=x.

Answer 2

2) reflection

Explanation:

Let's list down the coordinates of the triangle ABC and the triangle A'B'C'

A = (0, -4)

B = (3, -4)

C = (3, 0)

A' = (-4, 0)

B' = (-4, 3)

C' = (0, 3)

Here the transformation is a reflection and (x, y) -----> (y, x)

So, the triangle ABC reflected over the line x = y and got the image of triangle A'B'C'

Therefore, the answer is 2) reflection
