Alternate Interior Angles Alternate Exterior Angles Vertical Angles Corresponding Angles. Learn how to identify corresponding angles alternate interior angles alternate exterior angles and consecutive interior angles in this free math video tut. Alternate and corresponding and consecutive interior and vertical angles.
The angle pairs are on Alternate sides of the Transversal and they are on the Interior of the two crossed lines. A pair of corresponding angles is composed of one interior and another exterior angle. When the two lines being crossed are Parallel Lines the Alternate Exterior Angles are equal.
Alternate and co-interior angles when two straight lines are crossed by a transversal.
Look at the blue lines demonstrating the shape - the Z may be back to front as in the second example but the principle. That angles are created when two lines intersect each other. Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal. One way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles.
