1. prove: cbf ≅ edf using isometric (rigid) transformations.
outline the necessary transformations to prove cbf edf using a paragraph proof. be sure to name specific sides or angles used in the transformation and any congruency statements.

2. the congruency of mno and xyz can be proven using a reflection across the line bisecting . however, this congruency can also be proven using geometric postulates, theorems, and oz definitions. prove that the triangles are congruent using a two-column proof and triangle congruency theorems.

answer: 7270

step-by-step explanation:

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
