How Are The Alternate Interior Angles Theorem And The Alternate Exterior Angles Theorem Alike. The Alternate Exterior Angles Theorem states that When two parallel lines are cut by a transversal the. Similar to before angles 1 2 7 and 8 are EXTERIOR angles.
Lets represent it in a form if A then B. If alternate exterior angles are congruent then lines are parallel. Alternate interior angles are equal if the lines intersected by the transversal are parallel.
The Alternate Interior Angles Theorem states that when two parallel lines are cut by a transversal the resulting alternate interior angles are congruent.
Since k l by the Corresponding Angles Postulate 1 5. If lines are parralel them same side interior angles are suplementary and same side exterior angles are suplementary. The angles are positioned at the inner corners of the intersections and lie on opposite sides of the transversal. Lets represent it in a form if A then B.
