What is Triangle Congruence?

Back

Triangle Congruence refers to the condition where two triangles are considered congruent if their corresponding sides and angles are equal.

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a method to prove triangle congruence by showing two angles and the included side of one triangle are equal to the corresponding parts of another triangle.

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a method to prove triangle congruence by showing two sides and the included angle of one triangle are equal to the corresponding parts of another triangle.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a method to prove triangle congruence by showing all three sides of one triangle are equal to the corresponding sides of another triangle.

What is the significance of the congruence statement?

Back

A congruence statement indicates which parts of two triangles are congruent, allowing for clear communication of the relationships between the triangles.

Front

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

Back

If triangle ABC is congruent to triangle DEF, then angle A = angle D, angle B = angle E, angle C = angle F, and side AB = side DE, side BC = side EF, side AC = side DF.

What is the difference between congruence and similarity in triangles?

Back

Congruence means that triangles are identical in shape and size, while similarity means that triangles have the same shape but may differ in size.

Front

How can you determine if two triangles are congruent using the HL theorem?

Back

The HL (Hypotenuse-Leg) 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 triangles are congruent.

Front

What is the purpose of using congruence postulates in geometry?

Back

Congruence postulates are used to prove that two triangles are congruent, which helps in solving problems related to triangle properties and relationships.

Front

What is a corresponding angle in triangle congruence?

Back

A corresponding angle is an angle in one triangle that is equal to an angle in another triangle when the triangles are congruent.
