How Are The Alternate Interior Angles Theorem And The Alternate Exterior Angles Theorem Alike. Y 90 Angles in a triangle add up to 180. Exterior angles are also created by a transversal line crossing 2 straight lines.
The Alternate Interior Angles Theorem states that when two parallel lines are cut by a transversal the resulting alternate interior angles are congruent. The Alternate Exterior Angles Theorem states that When two parallel lines are cut by a transversal the. Alternate Interior Angles Theorem states that when two parallel lines are cut by a transversal the resulting alternate interior angles are congruent.
Alternate exterior angles are on the interior of two lines.
The Alternate Exterior Angles Theorem states that when two parallel lines are cut by a transversal the resulting alternate exterior angles are congruent. So in the figure below if k l then 2 8 and 3 5. If alternate exterior angles are congruent then lines are parallel. Y 90 Angles in a triangle add up to 180.
