Geometry Fall Final Review

Front

What is the definition of supplementary angles?

Back

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

Front

If one angle is 30 degrees, what is its supplement?

Back

The supplement of 30 degrees is 150 degrees.

Front

What is the definition of vertical angles?

Back

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

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside the two lines.

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 in relation to a transversal.

Front

What is an angle bisector?

Back

An angle bisector is a ray that divides an angle into two congruent angles.

Front

What is the contrapositive of a statement?

Back

The contrapositive of a statement is formed by negating both the hypothesis and conclusion and switching them.

Front

If p is parallel to q, what can be said about the angles formed by a transversal?

Back

If p is parallel to q, then corresponding angles are equal, alternate interior angles are equal, and consecutive interior angles are supplementary.

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

What is the formula for finding the measure of an exterior angle of a triangle?

Back

The measure of an exterior angle of a triangle is equal to the sum of the measures of the two opposite interior angles.
