the triangles are congruent by SSS. Similarly, if a and c are given (LH), then there is one value for b. The other legs must be congruent and the triangles are congruent by SSS. $16:(5 By the Pythagorean Theorem, the sides of a right triangle are always in the relationship a2 + b2 = c2. If a and b are given (LL), then there is one value for c.

triangle are congruent to the legs of another right triangle, then the triangles are congruent. HA Theorem (Hypotenuse-Angle Congruence): If the hypotenuse and one acute angle of one right triangle are congruent to the hypotenuse and corresponding acute angle of another right triangle, then the two triangles are congruent.

Yes. The triangles formed by the ladders, the ground, and the side of the house are right triangles. Each leg of one triangle is congruent to the corresponding leg of the other triangle, making the two triangles congruent by LL. The ladders form the hypotenuses of the triangles. Since the triangles are congruent, the hypotenuses are congruent.
