Test 1 - Congruent Triangles

Front

What are congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What does CPCTC stand for?

Back

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

Front

If ∠A is 48°, what is the measure of ∠F in congruent triangles?

Back

∠F is also 48° because corresponding angles in congruent triangles are equal.

Front

What is the relationship between corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal.

Front

How do you determine if two triangles are congruent?

Back

Two triangles can be proven congruent using criteria such as SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), or HL (Hypotenuse-Leg for right triangles).

Front

What is the measure of ∠D if ∠A ≅ ∠D?

Back

If ∠A ≅ ∠D, then the measure of ∠D is equal to the measure of ∠A.

Front

What is the significance of the symbol '≅'?

Back

The symbol '≅' indicates that two angles or segments are congruent.

Front

If triangle ABC is congruent to triangle DEF, what can be said about their corresponding sides?

Back

The corresponding sides of triangle ABC and triangle DEF are equal in length.

Front

What is the measure of ∠M if ∠A ≅ ∠M?

Back

If ∠A ≅ ∠M, then the measure of ∠M is equal to the measure of ∠A.

Front

What does it mean if two angles are congruent?

Back

If two angles are congruent, they have the same measure in degrees.
