Alternate Exterior Angles Converse Theorem. If two parallel lines are intersected by a transversal, then the alternate interior angles, alternate exterior angles,. Use the alternate exterior angles converse theorem.

Ppt 1 write a proof of the alternate exterior angles theorem. Consecutive interior angles theorem (theorem 3.4) if two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary. Converse of same side interior angles theorem algebra and.

So, We Can Conclude That Lines P And Q.


The converse of the theorem is also true: Use the alternate interior angles converse theorem. The alternate exterior angles theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent.

When A Transversal Intersects Two Parallel Lines, The Alternate Exterior Angles Formed Are Always Equal.


Exterior supplementary same side interior. Which lines, if any, must be parallel based on the given information? Thus c and d are parallel.

The Converse Of The Alternate Exterior Angle Theorem States That If Two Lines Are Cut By A Transversal And The Alternate Angles Are Congruent, Then The Lines Are Parallel.


The converse of the alternate interior angles theorem states that if two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel. The converse of the alternate exterior angles theorem converse of the alternate interior angles theorem students are probably already familiar with the alternate interior angles theorem, according to which if the transversal cuts across two parallel lines, then the alternate interior angles are congruent, that is, they have exactly the same angle measure. The converse of the alternate exterior angles theorem is also true:

Let's Recall The Alternate Interior Angles Theorem.


Two angles that lie on opposite sides of the transversal and outside the other two lines (exterior to the lines). In the same figure, ∠1 & ∠7 and ∠2 & ∠8 are the sets of alternate exterior angles. How to prove the converse of alternate exterior angles?

This Video Shows A Proof Of The Alternate Exterior Angle Converse.


Consecutive interior angles theorem (theorem 3.4) if two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary. Given xw xy zy prove δwxz δyzx a alternate interior. The pair of alternate exterior angles have the same measure i.e., ∠xba = ∠eds = 30°.
