Question

if we add the same triangle to two congruent triangles, are the sums congruent?

Answer 1

Answer:

true

Step-by-step explanation:

If two triangles are congruent, then each part of the triangle (side or angle) is congruent to the corresponding part in the other triangle. This is the true value of the concept; once you have proved two triangles are congruent, you can find the angles or sides of one of them from the other.
