Front

Solve for x if ∆ABC ≅ ∆DEF and x = ?

Back

x = 5.5.

Front

If two triangles are congruent and ∠C is 40°, what is the measure of ∠F?

Back

∠F is 50°.

Front

Complete the congruence statement: If ∆QRP ≅ ∆QRC, then ∠PQR ≅ ?

Back

∠PQR ≅ ∠CQR.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

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

Back

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

Front

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

Back

If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

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

Back

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

Front

What is the Hypotenuse-Leg (HL) theorem?

Back

In right triangles, if the hypotenuse and one leg of one triangle are equal to the hypotenuse and one leg of another triangle, the triangles are congruent.
