Geometry Semester 1 Review

Front

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

Back

180 degrees.

Front

What are vertical angles?

Back

Vertical angles are pairs of opposite angles formed by the intersection of two lines, and they are congruent.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the definition of supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

Back

x = 5.

Front

What type of angle pair are Angle 3 and Angle 6 if they are on opposite sides of the transversal and inside the two lines?

Back

Alternate interior angles.

Front

What is the definition of corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal.

Front

What is the relationship between the angles in a linear pair?

Back

Angles in a linear pair are supplementary.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

If two angles are complementary and one angle measures 30 degrees, what is the measure of the other angle?

Back

60 degrees.
