Geometry Fall Semester Exam Review

Front

What is the SAS similarity theorem?

Back

The SAS (Side-Angle-Side) similarity theorem states that if two triangles have one angle that is congruent and the lengths of the sides including that angle are in proportion, then the triangles are similar.

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is the definition of adjacent angles?

Back

Adjacent angles are two angles that share a common vertex and a common side but do not overlap.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

What is the midpoint of a line segment?

Back

The midpoint of a line segment is the point that divides the segment into two equal parts.

Front

If B is the midpoint of AC, and AC = 16, what is AB?

Back

AB = 8, since the midpoint divides the segment into two equal parts.

Front

What is the SSS congruence postulate?

Back

The SSS (Side-Side-Side) congruence postulate 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 ASA congruence postulate?

Back

The ASA (Angle-Side-Angle) congruence postulate 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 AAS congruence postulate?

Back

The AAS (Angle-Angle-Side) congruence postulate states that 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.
