Triangles are congruent when:All three sides are the same length (SSS congruency)Two sides and the angle between them are the same length (SAS congruency)Two angles and the side between them are the same length (ASA congruency)
Search Definition of Congruency
RHS congruency, or, right angle, hypotenuse and corresponding side.
No, he did not. In actual fact nobody "invented" congruency.

Search Definition of Congruency
They are theorems that specify the conditions that must be met for two triangles to be congruent.
You have acute, right, and obtuse triangles when referring to the measure of the largest angle, and you have equilateral, isosceles, and scalene triangles when referring to the congruency of the triangle's sides.

Because triangles add up to 180 degrees
RHS congruency, or, right angle, hypotenuse and corresponding side.
SSS, SAS, ASA, AAS, RHS. SSA can prove congruence if the angle in question is obtuse (if it's 90 degrees, then it's exactly equivalent to RHS).
