Answer:
m∠B=m∠R
Step-by-step explanation:
If you make the triangles congruent, you'll see many things like:
∠A=∠P
∠B=∠R
∠C=∠S
Line AB=Line RP
Line BC=Line RS
Line CA=Line SP
Out of the options, only m∠B=m∠R is true.
Answer:
m∠b = m∠r
Step-by-step explanation:
The triangle was reflected across line m.
A reflection is a rigid transformation. A rigid transformation does not change the measurement or size of a shape, so the pre-image and the image are congruent.
The angles on the pre-image corresponds to the angles on the image. This also is for line segments.
This means (for angle measurements):
Option D should be the correct answer.
