Question

If RST XYZ, which statement must be true?

Answer 1

Answer: $\angle{R}\cong\angle{X}$

Step-by-step explanation:

Given: $\triangle{RST}\cong\triangle{XYZ}$

We know that if two triangles are congruent then their corresponding parts are congruent (CPCTC).

Therefore, $\angle{R}\cong\angle{X}$

$\angle{S}\cong\angle{Y}$

$\angle{T}\cong\angle{Z}$

$\overline{RS}\cong\overline{XY}$

$\overline{ST}\cong\overline{YZ}$

$\overline{RT}\cong\overline{XZ}$

From the given option the right option is $\angle{R}\cong\angle{X}$

Answer 2

A because the angles match
