Alternate Interior Angles And Exterior Angles. When two lines are crossed by another line called the Transversal. 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.
As you can see the C shape may appear back to front but this doesnt affect the angle measurements. Two separate straight lines can both be crossed by a third line called a Transversal line. Exterior angles are.
Equal Alternate Interior Angles.
In this example these are two pairs of Alternate Exterior Angles. Alternate Interior Angles Alternate External Angles alternate interior angles proof of the alternate interior angle theorem proof of the converse of the alternate interior angle theorem alternate exterior angles proof of the alternate exterior angle theorem proof of the converse of the alternate. Angles 2 and 7 above as well as angles 3 and 6 are examples of alternate interior angles. 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.
