The bisector is a ray, a line or a portion of a line that enters the midpoint of the angle through the interior of the angle. Congruent angles are the same size as one another and they always contain an equal number of degrees. In the case of a 90-degree angle, a bisector splits the angle in half and creates two angles that are 45 degrees each. Lines that are the same length are also referred to as congruent.

Two types of geometric quadrilaterals, rectangles and squares, have two pairs of parallel lines and four right angles. In terms of these two shapes, they differ in that a square's sides are all equal length, whereas a rectangle generally has one longer pair and one shorter pair.

A quadrilateral with congruent diagonals is a rectangle or a square. All four angles of a rectangle and a square are right angles, making the diagonals congruent. The diagonals of a rectangle and a square also bisect each other.

Two objects are congruent if they have the same shape, dimensions and orientation. Congruent circles are circles that are equal in terms of radius, diameter, circumference and surface area. Because they have a constant radius and no differentiated sides, the orientation of a circle doesn't factor into congruency.
