Question

If two triangles satisfy the SAS criteria, describe the rigid motion(s) that would map one onto the other in the following cases.

The two triangles share a single common vertex.

Answer 1

A C D E

I got it right

Answer 2

Reflection, rotation

Explanation:

SAS congruency criteria:

• 2 sides of both triangles are equal

• the angle between these two sides of both triangles are equal

Then, if the two triangles share a single common vertex and satisfy the SAS criteria, both reflection or rotation would map one onto the other .
