Angles, Triangles & Parallel Lines

Front

What are Alternate Interior Angles?

Back

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

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of the transversal and outside the 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

If two parallel lines are cut by a transversal, what can be said about the Alternate Interior Angles?

Back

They are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the Corresponding Angles?

Back

They are equal.

Front

If two angles are supplementary, what is the sum of their measures?

Back
