Question

given the triangles below with sides and angles as marked. select the postulate or theorem that proves these triangles are congruent. side side side congruence postulate hypotenuse leg congruence theorem side angle side congruence postulate angle side angle congruence postulate angle angle side congruence theorem these triangles are not congruent.

Explanation:

The Side - Side - Side (SSS) Congruence Postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. In the given figure (a parallelogram divided by a diagonal), the two triangles formed have three pairs of congruent sides (opposite sides of a parallelogram are equal and the common diagonal is the third side).

Answer:

Side Side Side Congruence Postulate
