To unlock all 5,300 videos, If two lines in a plane are cut by a transversal so that any pair of alternate exterior angles is congruent, the lines are parallel. Alternate Exterior Angles Definition Alternate exterior angles are created when three lines intersect. Two alternate exterior angles are (2x – 14)° and (x + 4)° Prove whether the two exterior angles are congruent. An alternate exterior angle is equal to one another. Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. This contradicts Proposition 16 which states that an exterior angle of a triangle is always greater than the opposite interior angles. They are outside the two lines. In each illustration below, LINE 1 is a transversal of LINE 2 and LINE 3.In each illustration below, the following angles are alternate exterior angles: Understanding alternate interior and exterior angles, begins with becoming familiar with what is known as a Transversal Line. Alternate Exterior Angles : When two parallel lines are intersected by a transversal, the pair of angles formed outside the parallel lines is called alternate exterior angles. The alternate exterior angles theorem states that when two parallel lines are cut by a transversal the resulting alternate exterior angles are congruent. What are alternate angles in maths? The angles which are formed inside the two parallel lines,when intersected by a transversal, are equal to its alternate pairs. When two lines are crossed by a transversal the opposite angle pairs on the outside of the lines are an alternate exterior angle.

From the above-given figure, ∠1, ∠2, ∠7, ∠8 are the alternate exterior angles. Alternate exterior angles are congruent, meaning they have equal measure. What are alternate angles in maths. Check Maths definitions by letters starting from … In the above-given figure, you can see, two parallel lines are intersected by a transversal. If the transversalcuts across parallel lines (the usual case) then alternate exterior angles have the same measure. If the alternate angles are outside the two lines intersected by the transversal, they are called alternate exterior angles. Thus, They are found on the outer side of two parallel lines but on opposite side of the transversal. They are located "outside" the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate exterior angles.
