A ray that divides an angle into two congruent angles is called an angle bisector. The straight line cuts an angle in half, creating two equal angles.
Know MoreThe 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.
Learn MoreA polygon with four sides and four angles is called a quadrilateral. Quadrilaterals are two-dimensional, closed shapes with angle measurements that add up to 360 degrees.
Full Answer >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.
Full Answer >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.
Full Answer >Two rays that meet at a common endpoint are called an angle in geometry. In an angle, the rays are its sides and the endpoint is the vertex.
