WebThe alternate exterior angles have the same degree measures because the lines are parallel to each other. Alternate Interior Angles Theorem. If a transversal intersects two parallel … If a straight line intersects two or more parallel lines, then it is called a transversal line. When the coplanar lines are cut by a transversal, some angles are formed. Those angles are known as interior or exterior angles. Alternate angles are shaped by the two parallel lines crossed by a transversal. Consider the given … See more Based on the position of the angles, the alternate angles are classified into two types, namely 1.
