Parallel Lines & Angles (Congruent)

Front

What are parallel lines?

Back

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

Front

What is the definition of alternate interior angles?

Back

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

Front

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

Back

They are congruent.

Front

If angle 3 is 50 degrees, what is the measure of angle 7 if they are corresponding angles?

Back

50 degrees.

Front

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

Back

They are congruent.

Front

If angle 2 is 130 degrees, what is the measure of angle 3 if they are vertical angles?

Back

130 degrees.

Front

Name the angle relationship between angle 4 and angle 5 if they are on opposite sides of the transversal and inside the parallel lines.

Back

Alternate interior angles.

Front

What is the sum of the measures of angles on a straight line?

Back

180 degrees.
