Angles

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 Corresponding Angles?

Back

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

Front

What are Vertical Angles?

Back

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

Front

What are Adjacent Angles?

Back

Angles that share a common side and a common vertex but do not overlap.

Front

How do you identify Vertical Angles?

Back

Look for angles that are opposite each other at the intersection of two lines.

Front

What is a Transversal?

Back

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

Front

What is the relationship between Alternate Exterior Angles?

Back

They are equal when the lines are parallel.

Front

What is the sum of angles on a straight line?

Back

180 degrees.

Front

What is the sum of angles around a point?

Back

360 degrees.
