Angle-Side-Angle and Angle-Angle-Side Shortcuts
This video explains how two triangles are congruent if all three corresponding sides and all three corresponding angles are congruent. If two pairs of corresponding angles and the side between them are known to be congruent, the triangles are congruent. This shortcut is known as angle-side-angle (ASA). Another shortcut is angle-angle-side (AAS), where two pairs of angles and the non-included side are known to be congruent. ASA and AAS are important when solving proofs. (1:48)
