What Are Alternate Interior Angles And Alternate Exterior Angles Both Called Alternate. The angle pairs are on Alternate sides of the Transversal and they are on the Interior of the two crossed lines. Based on the position of the angles the alternate angles are classified into two types namely Alternate Interior Angles Alternate interior angles are the pair of angles on the inner side of the two parallel lines but on the opposite side of the transversal.
If lines are parallel then corresponding angles are congruent alternate interior angles are congruent and alternate exterior angles are congruent. Alternate exterior angles are always congruent. Here in the image shown below.
What is Transversal Line.
Alternate Interior Angles interior angles are formed when a transversal passes through two lines. The lines are parallel if alternate interior alternate exterior or corresponding angles are congruent. What are alternate angles in maths. What is Transversal Line.
