Math 2 Final Exam Review

Front

What is a congruent figure?

Back

Two figures are congruent if they have the same shape and size, meaning all corresponding sides and angles are equal.

Front

What does the acronym AAA stand for in triangle congruence?

Back

AAA stands for Angle-Angle-Angle, which is not a valid criterion for triangle congruence.

Front

What is the SAS criterion for triangle congruence?

Back

SAS stands for Side-Angle-Side, which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the ASA criterion for triangle congruence?

Back

ASA stands for Angle-Side-Angle, which states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the SSS criterion for triangle congruence?

Back

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

Front

What is the HL criterion for triangle congruence?

Back

HL stands for Hypotenuse-Leg, which applies to right triangles and states that if the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.

Front

What does the acronym SSA stand for in triangle congruence?

Back

SSA stands for Side-Side-Angle, which is not a valid criterion for triangle congruence.

Front

What is the relationship between similar triangles?

Back

Similar triangles have the same shape but not necessarily the same size; their corresponding angles are equal, and their corresponding sides are in proportion.

Front

How do you find the length of a side in similar triangles?

Back

To find the length of a side in similar triangles, set up a proportion using the lengths of corresponding sides.

Front

What is a bisector in geometry?

Back

A bisector is a line or segment that divides an angle or a segment into two equal parts.
