Angles

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal; they are equal.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 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

How do you find the missing angle in a linear pair?

Back

Subtract the known angle from 180 degrees.

Front

If two angles are vertical angles, what can you say about their measures?

Back

They are equal in measure.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

They are equal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

They are equal.
