which concept can be used to prove that the diagonals of a parallelogram bisect each other? congruent…

Brief Explanations:

In a parallelogram, we can show that the two - triangles formed by the diagonals are congruent. Using the properties of parallelograms (opposite sides are equal and parallel), we can prove congruence of these triangles. Once the triangles are proven congruent, we can show that the corresponding parts (the segments of the diagonals) are equal, meaning the diagonals bisect each other. Similar triangles, congruent rectangles, and similar rectangles are not relevant for this proof.

Answer:

congruent triangles
