Question

The figure below shows two triangles on the coordinate grid:

What set of transformations is performed on triangle ABC to form triangle A′B′C′?

Answers:
A: A translation 5 units up, followed by a 270-degree counterclockwise rotation about the origin

B: A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units up

C: A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units to the right

D: A translation 5 units to the right, followed by a 180-degree counterclockwise rotation about the origin

Answer 1

I think A. A translation 5 units up, followed by a 270-degree counterclockwise rotation about the origin

Answer 2

The answer is D

Explanation:

It is because for example use one of the coordinates like A (-1 , 1)

First five units to the right aka 4 , 1 then 180 { -x , -y} thus (-4 , -1) hope this helps!
