CPCTC

Front

What does CPCTC stand for?

Back

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

Front

What is the significance of CPCTC in geometry?

Back

CPCTC is used to prove that corresponding sides and angles of congruent triangles are equal.

Front

If two triangles are congruent, what can we say about their corresponding angles?

Back

The corresponding angles of congruent triangles are equal.

Front

If ΔABC ≅ ΔDEF, what can we conclude about ∠A and ∠D?

Back

∠A ≅ ∠D.

Front

What is the first step in proving triangles are congruent?

Back

Identify the congruence criteria (SSS, SAS, ASA, AAS, or HL).

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for 'Side-Side-Side,' meaning all three sides of one triangle are equal to the three sides of another triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for 'Side-Angle-Side,' meaning two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for 'Angle-Side-Angle,' meaning two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for 'Angle-Angle-Side,' meaning two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle.

Front

What does HL stand for in triangle congruence?

Back

HL stands for 'Hypotenuse-Leg,' which is a criterion for proving the congruence of right triangles.
