Yes. Alternate interior and alternate exterior angles are congruent.
Parallel lines cut by a transversal form congruent alternate interior angles.
If a transversal intersects a pair of lines and the alternate angles are congruent, the lines are parallel.
No. They are congruent. However, if one of the alternate angles is equal to 45, yes they would be complementary, but otherwise, no.
The lines are parallel. When a transversal intersects two lines, corresponding angles, alternate interior angles, and alternate exterior angles are congruent only if the lines are parallel. This is a fundamental property of parallel lines and transversals in geometry.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
Parallel lines cut by a transversal form congruent alternate interior angles.
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.
they are congruent i think
Sometimes they are.
If a transversal intersects a pair of lines and the alternate angles are congruent, the lines are parallel.
No. They are congruent. However, if one of the alternate angles is equal to 45, yes they would be complementary, but otherwise, no.
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.
The lines are parallel. When a transversal intersects two lines, corresponding angles, alternate interior angles, and alternate exterior angles are congruent only if the lines are parallel. This is a fundamental property of parallel lines and transversals in geometry.
Two angles that are congruent to each other and are on opposite sides of the parellel lines
Only if the lines cut by the transversal are parallel.
Only if the lines cut by the transversal are parallel.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
