Question

which theorem is used only for right triangles? hypotenuse-leg (hl) side-side-side (sss) angle-side-angle (asa) angle-angle-side (aas)

Explanation:

SSS, ASA, and AAS are triangle congruence theorems applicable to all types of triangles. The Hypotenuse-Leg (HL) theorem specifically applies only to right triangles, as it relies on the unique structure of right triangles (having a hypotenuse, the side opposite the right angle).

Answer:

Hypotenuse-Leg (HL)
