CPCTC Practice

Front

What does CPCTC stand for?

Back

CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent.

Front

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

Back

Their corresponding parts are congruent.

Front

Solve for x if \( \Delta ABC = \Delta DEF \) and x is the length of a side in triangle ABC.

Back

5.5

Front

If \( \angle C \) is 40° in triangle ABC and triangles ABC and DEF are congruent, what is \( \angle F \)?

Back

50°

Front

Complete the congruence statement for triangles OEG and OGE.

Back

OEG

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.

Front

List the criteria for triangle congruence (SSS, SAS, ASA, AAS, HL).

Back

1. SSS (Side-Side-Side) 2. SAS (Side-Angle-Side) 3. ASA (Angle-Side-Angle) 4. AAS (Angle-Angle-Side) 5. HL (Hypotenuse-Leg for right triangles).

Front

What is the Angle-Angle (AA) criterion for triangle similarity?

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

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

Back

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

Front

What is the significance of corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal.
