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 <em>congruent</em>.
The angles on the pre-image corresponds to the angles on the image. This also is for line segments.
This means (for angle measurements):
Angle A is congruent to Angle P Angle C is congruent to Angle S Angle B is congruent to Angle R Option D should be the correct answer.

Answer:
-3x² +6x -1 = 0
Step-by-step explanation:
x2 - 2x + = 4(x2-2x +1)-3
x² - 2x = 4x²-8x +4 - 3
x²-4x²-2x+8x = 4-3
-3x² +6x = 1
-3x² +6x -1 = 0
