Question

a
b side - angle - side congruent triangle theorem
c angle - angle - side congruent triangle theorem
d angle - side - angle congruent triangle theorem
e hypotenuse leg congruent triangle theorem
f not congruent

Explanation:

To determine if two triangles are congruent, we check the congruence theorems. The Side - Side - Side (SSS) Congruent Triangle Theorem states that if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent. In the given figure, the markings show that all three corresponding sides of the two triangles are equal.
