Short for "Angle-Side-Side." A false axiomatic test that is incorrectly used to prove that two triangles are congruent—that is, the corresponding sides and angles of two triangles are equal.
Like AAA for Angle-Angle-Angle, ASS is not sufficient to imply congruence of two triangles, because two triangles can have one common angle and two equal sides, yet they're not congruent.
