Answer:
Rule of 90° rotation( clockwise) is ( x , y ) →→ (y , -x)
and ( counter clockwise) is ( x , y ) →→ (-y , x).
Step-by-step 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).
