Alternate Interior Angles Vs Alternate Exterior Angles. When two lines are crossed by a transversal the opposite angle pairs on the outside of the lines are alternate exterior anglesOne way to identify alternate exterior angles is to see that they are the vertical angles of the alternate interior anglesAlternate exterior angles are equal to one another. Alternate exterior angles are those angles that have different vertices lie on the alternate sides of the transversal and are exterior to the lines.
In the diagram below transversal l intersects lines m and n. Click to see full answer. The alternate exterior angles that.
Angles that are in the area between the parallel lines like angle 2 and 8 above are called interior angles whereas the angles that are on the outside of the two parallel lines like 1 and 6 are called exterior angles.
Lets represent it in a form if A then B. Alternate exterior angles are those angles that have different vertices lie on the alternate sides of the transversal and are exterior to the lines. Also like with interior angles the above exterior angles are equal when a transversal line crosses 2 parallel lines. Geometry - Identifying Alternate Interior and Exterior Angles - YouTube.
