Angle properties of parallel lines

Complementary angles add upto give right angle = 90°

​Complementary angles

Supplementary angles add upto give right angle = 180°

​Supplementary angles

Linear pair of angles are supplementary. They add up to give 180°

Linear pair of angles

Vertically opposite angles are equal to each other.

Vertically Opposite angles

Corresponding angles are equal

​Corresponding angles

Alternate interior angles are equal

​Alternate interior angles

Alternate exterior angles are equal

Alternate exterior angles

The unknown angle is 53° because it is corresponding to the given angle
