What is the ASA Congruence Theorem?

Back

The ASA Congruence Theorem states that 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 is the AAS Congruence Theorem?

Back

The AAS Congruence Theorem states that if two angles and a non-included side of one triangle are equal to two angles and the 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, at least two angles and the included side (ASA) or two angles and a non-included side (AAS) are needed to prove congruence.

Front

What is the difference between ASA and AAS?

Back

ASA requires the side to be between the two angles, while AAS does not require the side to be between the two angles.

Front

If two triangles have two pairs of equal angles, what can be concluded?

Back

The triangles are congruent by the AAS theorem.

What is the significance of congruent triangles in geometry?

Back

Congruent triangles have the same size and shape, which allows for the transfer of properties and measurements.

Can the AAS theorem be used if only one angle is known?

Back

No, at least two angles and one side must be known to use the AAS theorem.
