A square is a four-verticed polygon. The shape is known as a regular quadrilateral because it has four equal sides and four 90-degree angles. The four corners, known as vertices, are where the sides meet.
A vertex is the common terminus of two or more rays or line segments in geometry. It is a point where two lines intersect in a more basic sense. The intersection of the edges or faces of a polygon or polyhedron forms the corners of the polygon or polyhedron. An angle is formed when two lines are united at a vertex. The included angle at each vertex of a square is referred to as the quadrilateral’s interior angle.
