A square is a polygon with four vertices. The shape has four equal sides and four 90-degree angles; thus, it is called a regular quadrilateral. The sides meet in four corners, which are called vertices.
Continue ReadingA vertex is defined in geometry as the common endpoint of two or more rays or line segments. In a more simplified meaning, it is a point where lines meet. This term is generally used to refer to the corners of a polygon or polyhedron formed by the intersection of the edges or faces. Two lines that are joined at a vertex form an angle. In a square, the included angle at each vertex is referred to as an interior angle of the quadrilateral.
