CPCTC

Front

What does CPCTC stand for?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.'

Front

When should CPCTC be used in a proof?

Back

CPCTC should always be used at the end of a proof.

Front

What is the SSS postulate?

Back

The SSS postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.

Front

What is the SAS postulate?

Back

The SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Front

What is the Reflexive Property?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

Front

What is the purpose of using congruence postulates in geometry?

Back

Congruence postulates are used to prove that two triangles are congruent based on specific criteria.

Front

Can you name the three main triangle congruence postulates?

Back

The three main triangle congruence postulates are SSS, SAS, and ASA (Angle-Side-Angle).

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for 'Angle-Side-Angle,' which is a postulate used to prove triangle congruence.

Front

What is the difference between congruence and similarity in triangles?

Back

Congruence means that two triangles are identical in shape and size, while similarity means that two triangles have the same shape but may differ in size.

Front

What is the importance of proving triangles congruent in geometry?

Back

Proving triangles congruent allows us to establish relationships between angles and sides, which is fundamental in solving geometric problems.
