Corresponding angles are the angles that occupy the position in matching corners when a line called a transversal crosses two lines. These corresponding angles are equal or congruent if the transversal crosses two parallel lines.
There are eight angles formed when a transversal crosses two parallel lines. Besides corresponding angles, there are other types of angles formed, including vertical angles, interior angles and exterior angles. While interior angles are the four angles that occupy the space between the parallel lines, the angles that are on the outer side of the parallel lines are exterior angles.
Some other types of angles formed are adjacent angles, consecutive interior angles, alternate interior angles and alternate exterior angles. Adjacent angles form a linear pair or are supplementary, which means that the sum of their angle measurements is equal to 180 degrees.
