Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
A parallelogram with no right angles and four congruent sides is a Rhombus.
4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
A pair of congruent angles are those which measure the same size. Therefore, two congruent angles can be of any size, as long as they are of an identical size.Angles of 90 degrees are commonly referred to as "right angles".
Rhombus: A Rhombus has four congruent sides but no right angles.
