Triangle congruence Shortcuts Practice

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a rule 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.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a rule 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 SSS stand for in triangle congruence?

Back

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

Front

What does AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a rule that states 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.

Front

What does SSA stand for in triangle congruence?

Back

SSA stands for Side-Side-Angle, which does not guarantee triangle congruence. Two triangles can have two sides and a non-included angle equal but may not be congruent.

Front

When can you use the SAS rule?

Back

You can use the SAS rule when you know two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

When can you use the ASA rule?

Back

You can use the ASA rule when you know two angles and the included side of one triangle are equal to two angles and the included side of another triangle.

Front

When can you use the SSS rule?

Back

You can use the SSS rule when you know all three sides of one triangle are equal to all three sides of another triangle.

Front

When can you use the AAS rule?

Back

You can use the AAS rule when you know two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle.

Front

Can SSA be used to prove triangle congruence?

Back

No, SSA cannot be used to prove triangle congruence because it can lead to ambiguous cases where two different triangles can be formed.
