Parallel Lines & Transversals Geo Ch 3 Half

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

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

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines when cut by a transversal.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the parallel lines.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

How do you find the sum of interior angles in a polygon?

Back

Use the formula (n-2) × 180°, where n is the number of sides.

Front

What are remote interior angles?

Back

Angles that are not adjacent to a given exterior angle but are inside the polygon.

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 their sum?

Back

180°.
