Question

Which triangles (if any) can be shown to be congruent using a rotation?

A) 1 and 2
B) 2 and 3
C) 1 and 3
D) none

Answer 1

Explanation:

alright, lets get started.

There are three triangles are given .

For 1 and 2 to be congruent, a triangle needs to be reflected. Means reflection is required.

For 1 and 3 to be congruent, a triangle needs to be reflected and rotated both, means reflection and rotation both are required.

For 2 and 3, triangle needs to be rotated only.

Means for triangle 2 and 3 to be congruent, it needs rotation.

So, the answer is 2 ans 3 option B : answer

Hope it will help :)
