Thus the formal definition of corresponding sides can be stated as follows: In two or more different plane figures, the sides that are in the same position but in different plane figures are called corresponding sides.
Corresponding angles are the pairs of angles on the same side of the transversal and on corresponding sides of the two other lines. These angles are equal in degree measure when the two lines intersected by the transversal are parallel.
