Proving Triangles are Congruent - YourTeacher.com - Math Help

For a complete lesson on proving triangles are congruent, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn the following postulates related to congruent triangles and triangle proofs. If the three sides of one triangle are congruent to the three sides of another triangle, then the triangles are congruent (Side-Side-Side or SSS). If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent (Side-Angle-Side or SAS). 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 (Angle-Side-Angle or ASA). Students are then asked to determine whether given triangles are congruent, and name the postulate that is used.

Angle Side Side (ASS)

[lulugal31]

fuck studing for a spanish test, history, and geometry

[mariezette13]

can we consider the part D as Angle Side Side (ASS) ?

can you post about the theorems ;)

@Kbanasko How'd the exam go?

[1234cappicorn]

@roshni62796 yeah you have point

[Zero6sixes666]

i wish ASS was a postulate
