exists and is an alternate of . LL Congruence theorem says: If the two legs of one right triangle are congruent to the two legs of another right triangle, then the two right triangles are congruent.
Proof:A right angle is an angle whose degree measure is 90.Therefore, mABC. is 90 and mDEF is 90.Since mABC and mDEF are both equal to the same. quantity,they are equal to each other.Since ABC and DEF have equal mea-. sures, they are congruent. If two angles are right angles, then they are congruent.
