Question

A triangle is rotated 90 degrees about the origin. Which rule describes the transformation?

Answer 1

X (x,y) y, -x)

Hope this helps

Answer 2

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).
