Exam Review: Unit 3

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

Front

What is the AAS criterion for triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where 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

Define SAS in the context of triangle congruence.

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What does ASA mean in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a criterion for triangle congruence where two angles and the included side of one triangle are equal to two angles and the corresponding included side of another triangle.

Front

How do you find the value of x in a triangle?

Back

To find the value of x in a triangle, use the properties of triangles such as the sum of angles in a triangle equals 180 degrees or apply congruence criteria.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

Can a triangle have sides of lengths 3, 8, and 9?

Back

Yes, a triangle can have sides of lengths 3, 8, and 9 because they satisfy the triangle inequality theorem.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

How do you find the measure of a missing angle in a triangle?

Back

To find the measure of a missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the definition of a congruent triangle?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.
