Answer:

Rule of 90° rotation( clockwise) is ( x , y ) →→ (y , -x)

and ( counter clockwise) is ( x , y ) →→ (-y , x).

Explanation:

Given : A triangle is rotated 90 degrees about the origin.

To find : Which rule describes the transformation?

Solution : We have given A triangle is rotated 90 degrees

By the rotation rule of 90°( clockwise) is ( x , y ) →→ (y , -x).

Rule of 90°( counter clockwise) is ( x , y ) →→ (-y , x).

Therefore, Rule of 90° rotation( clockwise) is ( x , y ) →→ (y , -x)

and ( counter clockwise) is ( x , y ) →→ (-y , x).
