Question

which criterion, if any, could prove the triangles are congruent?
a. asa
b. sas
c. hl
d. none

Explanation:

Step1: Recall congruence criteria for right - angled triangles

For right - angled triangles, the HL (Hypotenuse - Leg) criterion states that if the hypotenuse and one leg of a right - angled triangle are equal to the hypotenuse and one leg of another right - angled triangle, then the two triangles are congruent.

Step2: Analyze the given triangles

The given triangles are right - angled (as there are right angles). We assume the marked equal sides are legs and the non - marked sides (the slanting sides) are hypotenuses.

Answer:

C. HL
