What does CPCTC stand for in geometry?

Back

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

Front

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

Back

The corresponding angles of congruent triangles are equal.

Front

If ΔABC ≅ ΔXYZ, what is the relationship between ∠A and ∠M?

Back

∠A ≅ ∠M.

Front

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

Back

The symbol '≅' indicates that two figures are congruent.

Front

If ΔDEF ≅ ΔRST, what can we conclude about the sides DE and RS?

Back

DE = RS.

Front

What is the first step in proving two triangles are congruent?

Back

Identify and show that at least one pair of corresponding sides or angles are congruent.

Front

What are the criteria for triangle congruence?

Back

The criteria for triangle congruence are SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and HL (Hypotenuse-Leg for right triangles).

Front

How can you determine if two angles are corresponding angles?

Back

Two angles are corresponding angles if they are in the same relative position at each intersection where a straight line crosses two others.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

In the context of triangle congruence, what does the term 'corresponding parts' refer to?

Back

'Corresponding parts' refer to the sides and angles of the triangles that match up when the triangles are congruent.
