If you have two right triangles and the ratio of their hypotenuses is the same as the ratio of one of the sides, then the triangles are similar. (You know the missing side using the Pythagorean Theorem, and the missing side must also have the same ratio.) So I suppose that Sal left off the RHS similarity postulate.Apr 23, 2021 · For triangles to be congruent by “side, angle, side” you need to have two congruent sides that together form the vertex of the same angle.
