ASA and AAS △ Congruence

Front

What does ASA stand for in triangle congruence?

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.

What does AAS stand for in triangle congruence?

Back

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

Can two triangles be congruent if only one angle and one side are known?

Back

No, two triangles cannot be proven congruent with only one angle and one side; more information is needed, such as another angle or side.

What is the difference between ASA and AAS?

Back

The difference is that ASA requires the included side between the two angles to be known, while AAS allows for a non-included side to be known.

Front

What is the significance of congruent triangles in geometry?

Back

Congruent triangles have the same size and shape, which means their corresponding sides and angles are equal, allowing for various applications in proofs and real-world problems.

What theorem can be used to prove triangles congruent if two sides and the included angle are known?

Back

The Side-Angle-Side (SAS) theorem can be used to prove triangles congruent if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

What is the Side-Side-Side (SSS) theorem?

Back

The SSS theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.
