Two right triangles will be congruent under a variety of scenarios besides HL. One of which is the following: If the hypotenuse and an acute angle of one right triangle are equal, respectively, to the hypotenuse and an acute angle of another, then the right triangles are congruent. (Use the two triangles below, mark them up and then
decide on which congruence theorem will prove that the two are congruent (SAS, SSS, ASA, AAS or HL).

Explain why this must be true.
