Which postulate or theorem proves the triangle congruent?

• ASA: Angle Side Angle

• SAS: Side Angle Side

• SSA: Side Side Angle

• SSS: Side Side Side

• Not enough information

Name the postulate, if possible, that makes the triangles congruent.

• SSS

• SAS

• ASA

• HL

Why are these two triangles congruent?

• SSS

• ASA

• AAS

• SSA <--- not the other way around

CAB and ZXY are congruent, why?

• SSS

• SAS

• AAS

• HL

The three S' in the SSS Postulate stand for...

• Super, Slimy, Salamanders.

• Side-Side-Side

• Single-Sided-Square.

What is the definition of the SSS Postulate?

• If two sides of a triangle are congruent then the base angles are congruent.

• Corresponding Parts of Congruent Triangles are Congruent.

• if a traversal interjects parallel lines then the corresponding angles are congruent.

• If three sides in one triangle are congruent to 3 sides in another triangle then the two triangles are congruent.

What does CPCTC stand for?

• Corresponding Parts of Congruent Triangles are Congruent.

• If the hypotenuse and leg of one triangle and the leg of another triangle then the triangles are congruent.

• If two sides of a triangle are congruent then the base angles are congruent.

• If a point is on the angle bisector, then the point is equidistant from the sides of the angle.
