A right angle is an angle whose measure is 90 degree. Two lines which are perpendicular to each other formed a right angle. Unlike acute and obtuse angles all right angles are congruent as all of them measure 90 degree.
Angle  Wikipedia
Equivalence angle pairs. Angles that have the same measure (i.e. the same magnitude) are said to be equal or congruent.An angle is defined by its measure and is not dependent upon the lengths of the sides of the angle (e.g. all right angles are equal in measure).
Perpendicular  Wikipedia
In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees).The property extends to other related geometric objects.
