A polygon with three corners is a triangle, which also has three sides. Four-sided polygons are known as quadrilaterals. Examples of quadrilaterals include the square, rectangle and parallelogram. Common three-dimensional shapes include the cube, triangular prism, cone, cylinder and tetrahedron. None of the shapes have three corners, or vertices. Some, such as the cylinder, have no corners. Others, such as the tetrahedron, have four vertices.
