Question

6.) rotate △qst 90° clockwise about the origin.
6b.) the coordinates of n’ are:
6c.) true or false?
△qts is congruent to △q’t’s’.

Explanation:

Step1: Recall rotation rule

The rule for a 90 - degree clockwise rotation about the origin is $(x,y)\to(y, - x)$.

Step2: Analyze congruence

A rotation is a rigid transformation. Rigid transformations preserve side - lengths and angles. So, the pre - image and the image of a rotation are congruent.

Answer:

6b.) (No point N is given in the problem description, so cannot answer this part)
6c.) True
