CPCTC Practice

Front

What does CPCTC stand for in geometry?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.' It is a principle used to prove that corresponding angles and sides of congruent triangles are equal.

If ∠C is 40° in triangle ABC and triangle DEF is congruent to triangle ABC, what is the measure of ∠F?

Back

∠F is also 40° because corresponding angles in congruent triangles are equal.

What is the significance of the symbol '≅' in geometry?

Back

The symbol '≅' indicates that two figures are congruent, meaning they have the same shape and size.

Front

If two triangles have two pairs of equal angles, what can be concluded about the triangles?

Back

The triangles are congruent by the Angle-Angle (AA) criterion for triangle congruence.

Front

What is the Angle-Side-Angle (ASA) criterion for triangle congruence?

Back

The ASA criterion states that 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.
