Unit 3 Part 2 Final Exam Review

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a postulate 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.

Front

What does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a postulate 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 AAS stand for in triangle congruence?

Back

AAS stands for Angle-Angle-Side, a postulate 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 is the relationship between corresponding angles in congruent triangles?

Back

All corresponding angles in congruent triangles are congruent.

Front

What additional information is needed for two triangles to be congruent by SAS?

Back

You need to know the length of one side that is not included between the two angles.

What additional information is needed for two triangles to be congruent by SSS?

Back

You need to know the length of one side that is not included between the two sides.

Front

If two triangles have two sides and the included angle equal, what postulate can be used to prove congruence?

Back

SAS (Side-Angle-Side) postulate.

Front

If two triangles have three sides equal, what postulate can be used to prove congruence?

Back

SSS (Side-Side-Side) postulate.

Front

Can two triangles be congruent if only one angle is known?

Back

No, you need more information, such as sides or additional angles.
