What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a postulate used to prove that two triangles are congruent if two angles and the non-included side of one triangle are equal to the corresponding parts of another triangle.

Front

What is the SSS congruence theorem?

Back

SSS stands for Side-Side-Side, a theorem that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a postulate that states if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

What is the ASA congruence theorem?

Back

ASA stands for Angle-Side-Angle, a theorem that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What does it mean if two triangles are congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

What is the significance of the congruence statement ΔABC ≅ ΔEDC?

Back

This statement indicates that triangle ABC is congruent to triangle EDC, meaning all corresponding sides and angles are equal.

Front

What is the purpose of triangle congruence theorems?

Back

Triangle congruence theorems are used to determine if two triangles are congruent based on their sides and angles, which helps in solving geometric problems.

Front

What is the meaning of the term 'angle' in geometry?

Back

An angle is formed by two rays (sides) that share a common endpoint (vertex) and is measured in degrees.

Front

How can you identify the correct name for an angle?

Back

The correct name for an angle is typically based on its vertex and the points on each ray, such as angle KVJ for vertex V.

Front

What does 'not enough information' mean in triangle congruence?

Back

'Not enough information' means that the given data is insufficient to determine if the triangles are congruent.
