Question

question 28 of 28 which of the following theorems verifies that △def≅△stu? a. la b. hl c. ha d. ll

Explanation:

We see that both triangles have a right - angle, a pair of congruent legs (the marked sides), and a pair of congruent acute angles. The LA (Leg - Angle) theorem states that if one leg and an acute angle of one right - triangle are congruent to one leg and the corresponding acute angle of another right - triangle, then the two right - triangles are congruent. Here, we have a leg and an acute angle congruent in the two right - triangles.

Answer:

A. LA
