What does the Side-Side-Side (SSS) Congruence Theorem state?

Back

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

What does the Side-Angle-Side (SAS) Congruence Theorem state?

Back

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

What does the Angle-Side-Angle (ASA) Congruence Theorem state?

Back

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

What is the significance of corresponding parts of congruent triangles?

Back

Corresponding parts of congruent triangles are equal, meaning that if two triangles are congruent, all their corresponding sides and angles are also equal.

How can you determine if two triangles are congruent using the Hypotenuse-Leg (HL) theorem?

Back

The HL theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the two triangles are congruent.

How do you solve for a missing angle in congruent triangles?

Back

To solve for a missing angle in congruent triangles, use the fact that the sum of angles in a triangle is 180 degrees and apply the congruence properties.
