Unit 2 Review--Final Exam

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the Side-Side-Side (SSS) Triangle Congruence Theorem?

Back

The SSS Triangle Congruence Theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the Side-Angle-Side (SAS) Triangle Congruence Theorem?

Back

The SAS Triangle Congruence Theorem states that 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 is the Angle-Side-Angle (ASA) Triangle Congruence Theorem?

Back

The ASA Triangle 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.

Front

What is the definition of a parallelogram?

Back

A parallelogram is a four-sided figure (quadrilateral) with opposite sides that are parallel and equal in length.

Front

What can be concluded about the angles in a parallelogram?

Back

In a parallelogram, opposite angles are equal, and consecutive angles are supplementary (add up to 180 degrees).

Front

What is the Isosceles Triangle Theorem?

Back

The Isosceles Triangle Theorem states that if two sides of a triangle are equal, then the angles opposite those sides are also equal.

Front

What is the Perpendicular Bisector Theorem?

Back

The Perpendicular Bisector Theorem states that any point on the perpendicular bisector of a segment is equidistant from the endpoints of the segment.

Front

How do you determine if two triangles are congruent using corresponding parts?

Back

If two triangles are congruent, then their corresponding sides and angles are equal.

Front

What is the significance of diagonal bisectors in triangles?

Back

A diagonal bisector divides the angle into two equal parts, which can help in proving triangle congruence.
