Applying Angle Relationships

Front

What are supplementary angles?

Back

Front

What is the relationship between same side interior angles?

Back

They are angles that lie on the same side of the transversal and between the two lines.

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.

Front

If two angles are supplementary and one angle measures 70 degrees, what is the measure of the other angle?

Back

110 degrees.

Front

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

Back

Front

If angle 1 and angle 2 are vertical angles, and angle 1 measures 50 degrees, what is the measure of angle 2?

Back

50 degrees.

Front

What is the relationship between alternate interior angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

If angle 3 is 40 degrees and angle 4 is a same side interior angle, what is the measure of angle 4?

Back

140 degrees.

Front

What is the definition of a transversal?

Back

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