ASA Postulate If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent. H K M O N J

Included Sides An included side is very similar to included angles, however an included side is now a side that is stuck between two specific angles or you can think of it as a side that helps create both indicated angles. N O M
