Assuming a geometry in which Euclid's Fifth Postulate is considered true...
Yes, someone can prove that.
converse of the alternate exterior angles theorem
they are angles that are usually parallel and that crossed the line that are oppsite from each other
Alternate angles are equal and lie on opposite sides of the transversal line that cuts through the parallel lines
alternate interior and alternate exterior angles
Those ones, there!
converse of the alternate exterior angles theorem
When a line transverses parallel lines the alternate exterior angles of that line are equal
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
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.
alternate exterior angles theorem
they are angles that are usually parallel and that crossed the line that are oppsite from each other
yes
Then the alternate angles created would be equal in size.
3.1 or alternate interior angles ....then the lines are parallel
Only if the lines cut by the transversal are parallel.
When parallel lines are cut through by a transversal line the alternate angles are equal
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.
