What is the rule about alternate interior angles?
They are supplementary angles / The sum of their measures are 180 degrees.
What do you call interior angles and exterior angles on the same side of a transversal cutting through parallel lines?
There are 4 types which are:- 1 Corresponding equal angles 2 Alternate equal angles 3 Vertical opposite equal angles 4 Interior supplementary or allied angles
Are alternate angles congruent?
Yes. Alternate interior and alternate exterior angles are congruent.
What is meant by alternate Interior angles?
Alternate interior angles are equal on a transversal that passes through parallel lines.
What angles are inside parallel lines on a transversal?
Alternate and supplementary

What are the conditions that guarantee parallelism?
Parallel lines are lines that are coplanar (lying on the same plane) and do not intersectwhen cut by a transversal,corresponding angles formed by line n are equal in measure,alternate interior angles are equal in measures,the measures of alternate exterior angles are equal,consecutive interior angles are supplementary,consecutive exterior angles are supplementary.
Are the alternate interior angles of two parallel lines cut by a transveral always interior?
Yes. "Alternate interior" angles are always interior. Angles that are not interior as well as alternate are never accurately described as "alternate interior" angles.
What are two pairs of alternate interior angles?
They are 4 alternate interior angles.
Uses of parallel lines cut by a transversal?
There's lots of useful things you can discover when parallel lines are cut by a transversal, most of them having to do with angle relationships. Corresponding angles are congruent, alternate interior angles are congruent, same side or consecutive interior angles are supplementary, alternate exterior angles are congruent, and vertical angles are congruent.

Are alternate angles congruent?
Yes. Alternate interior and alternate exterior angles are congruent.
What types of angles are equal?
alternate interior and alternate exterior angles
What is meant by alternate Interior angles?
Alternate interior angles are equal on a transversal that passes through parallel lines.
Why are alternate interior angles and alternate exterior angles both called alternate?
Both alternate interior and alternate exterior angle pairs lie on opposite sides of the transversal.
What angles are inside parallel lines on a transversal?
Alternate and supplementary
Are consecutive interior angles of a rectangle are supplementary?
Yes. Two angles are suplementary if their sum is 180 degrees. All interior angles in a rectangle are 90 degrees, so any pair of these angles is supplementary.
