Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. You rotate triangle ABC, with vertices A(-3, 1), B(-2, 2), and C(-3, 4), 90° counterclockwise about the origin to form triangle A′B′C′. Match each vertex of triangle A′B′C′ to its coordinates.

A(-3, 1) to (1, 3)

B(-2, 2) to (2, 2)

C(-3, 4) to (4, 3)  

Step-by-step explanation:

As we know that

The Rule for going 90 degrees is counterclockwise

Like

(x, y) becomes (y, -x)

Therefore

For the coordinates of A are (-3,1)

the new point will be  (1,3)

For the coordinates of B  (-2,2)

The new coordinates will be  (2,-2)

For the coordinates of B  (-3,4)

The new coordinates will be (4,3)

Hence, the matching is as follows

A(-3, 1) to (1, 3)

B(-2, 2) to (2, 2)

C(-3, 4) to (4, 3)  

$12. that is my answer.
