Question

If ARST = XYZ, which statement must be true?

Answer 1

Answer:

The answer is B.

Step-by-step explanation:

That's because in A. angle S and angle Z aren't corresponding in the congruence of RST and XYZ.  

In C. line RS and line ST can' be proven to be congruent because they arent a part of the what we know which is RST is congruent to XYZ. It says nothing about RS being congruent to ST.

And D. has the same problem as A. with the line ST and line XZ not corresponding the what we know. If it had said ST is congruent to YZ, or that RT is congruent to XZ then it would be true. Because RST is congruent to XYZ. And R corresponds to X, S corresponds to Y, and T corresponds to Z.

So B. would be the answer because R and X correspond to one another because it's written as RST ans XYZ and both R and X are the first letters represented in both triangles.
