alternate angles, transversal

Front

What are alternate angles?

Back

Angles that are on opposite sides of a transversal and between two lines.

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 is a transversal?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

They are equal.

Front

If angle 1 is 76 degrees, what is the measure of angle 7 if angle 7 is an exterior angle?

Back

104 degrees.

Front

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

Back

They are equal.

Front

How do you find the measure of an angle when given its supplementary angle?

Back

Subtract the measure of the known angle from 180 degrees.

Front

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

Back

180 degrees.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and between the two lines; they are supplementary.
