Parallel lines cut by a transversal form congruent alternate interior angles.
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
Alternate interior angles are equal on a transversal that passes through parallel lines.
When a line transverses parallel lines the alternate exterior angles of that line are equal
Alternate angles are where two parallel lines have a line through them.
Parallel lines cut by a transversal form congruent alternate interior angles.
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
Alternate interior angles are equal on a transversal that passes through parallel lines.
When a line transverses parallel lines the alternate exterior angles of that line are equal
If a transversal intersects a pair of lines and the alternate angles are congruent, the lines are parallel.
Then the alternate angles created would be equal in size.
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
Yes. "Alternate interior" angles are always interior. Angles that are not interior as well as alternate are never accurately described as "alternate interior" angles.
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
Alternate Exterior Angles are created where a transversal crosses two (usually parallel) lines. Each pair of these angles are outside the parallel lines, and on opposite sides of the transversal.
