Question

the ll congruence theorem for right triangles is a special case of the _____.
a. aas theorem or sss postulate
b. sas postulate or sss postulate
c. sas postulate or asa postulate
d. aas theorem or asa postulate

Explanation:

The LL (Leg - Leg) congruence theorem for right - triangles states that if the two legs of one right - triangle are congruent to the two legs of another right - triangle, the triangles are congruent. In the SAS (Side - Angle - Side) postulate, if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, the triangles are congruent. In right - triangles, the right angle is the included angle between the two legs. Also, if we consider the two legs and the hypotenuse (which can be found using the Pythagorean theorem), it relates to the SSS (Side - Side - Side) postulate as well.

Answer:

B. SAS postulate or SSS postulate
