A polygon with 4 sides is called

Regular polygon - A polygon having all sides of equal length and the interior angles of equal measure is known as a regular polygon i.

A quadrilateral is a polygon that has exactly four sides. This also means that a quadrilateral has exactly four vertices, and exactly four angles. Discussions of 2-D shapes sometimes refer only to the boundary the line segments that form the edges of the figure or to the interior as well. The usual definitions of polygons, however, refer only to the line segments that form the edges of the polygon. Most of the time, context will make clear what you mean, but you should remain aware that in some cases you may need to clarify.

A polygon with 4 sides is called

In geometry a quadrilateral is a four-sided polygon , having four edges sides and four corners vertices. The word is derived from the Latin words quadri , a variant of four, and latus , meaning "side". It is also called a tetragon , derived from Greek "tetra" meaning "four" and "gon" meaning "corner" or "angle", in analogy to other polygons e. Since "gon" means "angle", it is analogously called a quadrangle , or 4-angle. Quadrilaterals are either simple not self-intersecting , or complex self-intersecting, or crossed. Simple quadrilaterals are either convex or concave. The interior angles of a simple and planar quadrilateral ABCD add up to degrees of arc , that is [1]. All non-self-crossing quadrilaterals tile the plane , by repeated rotation around the midpoints of their edges. A self-intersecting quadrilateral is called variously a cross-quadrilateral , crossed quadrilateral , butterfly quadrilateral or bow-tie quadrilateral. The two diagonals of a convex quadrilateral are the line segments that connect opposite vertices.

Article Talk. The four maltitudes of a convex quadrilateral are the perpendiculars to a side—through the midpoint of the opposite side. A regular 4 sided polygon is a square. The interior angles of a simple and planar quadrilateral ABCD add up to degrees of arc , that is [1]. In the latter case the quadrilateral is a tangential quadrilateral. These special cases, called cyclic quadrilaterals, include rectangles and therefore squares and isosceles trapezoids, but also other shapes that have no special name of their own. From Bretschneider's formula it directly follows that the area of a quadrilateral satisfies. Some K-8 curricula also include kites G and, in some definitions H. Simple quadrilaterals are either convex or concave. Quadrilateral A quadrilateral is a polygon that has exactly four sides. Retrieved Forum Geometricorum. Tools Tools.

This is called the isoperimetric theorem for quadrilaterals. In the classification scheme below, rectangles F and B have the right hand column to themselves, but parallelograms are not grouped in a way that excludes A , which is not a parallelogram. Maths Program. If a convex quadrilateral has the consecutive sides a , b , c , d and the diagonals p , q , then its area K satisfies [37]. The two bimedians in a quadrilateral and the line segment joining the midpoints of the diagonals in that quadrilateral are concurrent and are all bisected by their point of intersection. Other, more symmetric formulas for the lengths of the diagonals, are [27]. Another possible way to classify quadrilaterals is by examining their diagonals. The area of a quadrilateral ABCD can be calculated using vectors. Forum Geometricorum. Cyclic quadrilaterals: For some quadrilaterals, it is possible to pass a single circle through all four of its vertices.
