Two angles are congruent if they have the same shape and size, but are in different positions.

If two angles form a linear pair, then the sum of the angles must equal 180 degrees.

If the angles are congruent, they must have the same value, therefore the angle = 180/2 = 90 degrees.

90 degrees is a right angle, so both angles are right angles.
