Front

What does CPCTC stand for?

Back

Corresponding Parts of Congruent Triangles are Congruent

Front

What are the two missing pieces of information in triangle proofs?

Back

Reflexive Property, SSS (Side-Side-Side)

Front

What is the 'statement' for step 3 of the proof if HA=AH?

Back

HA=AH

Front

What is the 'statement' for step 3 of the proof if HT=TA?

Back

HT=TA

Front

Determine if the triangles are congruent: If the sides and angles are not equal, what is the conclusion?

Back

Not congruent

Front

What is the SAS (Side-Angle-Side) theorem?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the ASA (Angle-Side-Angle) theorem?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the AAS (Angle-Angle-Side) theorem?

Back

If two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the triangles are congruent.

Front

What does the Reflexive Property state?

Back

Any geometric figure is congruent to itself.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.
