Geometry for Elementary School/The Side-Angle-Angle congruence theorem

The Angle-Side-Angle congruence theorem The Right angle-Hypotenuse-Side congruence theorem In this chapter, we will discuss yet another congruence theorem, the Side-Angle-Angle congruence theorem, usually abbreviated as SAA(or AAS - Angle-Angle-Side , commonly used in India) The Angle-Side-Angle congruence theorem Given two triangles and such that their sides are equal, hence:File:AAS example.png The angle equals . (they have the same angle ) The angle equals . (they have the same angle ) The side equals . (they have the same side ) Then the triangles are congruent and their other angles and sides are equal too.
