Assessment: Angle Relationships

Front

What is a straight angle?

Back

A straight angle is an angle that measures exactly 180 degrees.

Front

What are corresponding angles?

Back

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

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line, and their measures add up to 180 degrees.

Front

What are vertical angles?

Back

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

Front

What is an obtuse angle?

Back

An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is the sum of angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that lie between two parallel lines and on opposite sides of a transversal. They are congruent.

Front

What is the relationship between supplementary angles?

Back

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