Polygon with 4 sides is called

Quadrilaterals are polygons with four sides hence the beginning "quad", which means "four". A polygon with non-equal sides is called irregularso the figure that you are describing is an irregular quadrilateral.

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. Elementary school curricula typically have children learn the names of special subsets of quadrilaterals with particular features. Here we list the special names.

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. The two bimedians of a convex quadrilateral are the line segments that connect the midpoints of opposite sides. The four maltitudes of a convex quadrilateral are the perpendiculars to a side—through the midpoint of the opposite side. The area can be expressed in trigonometric terms as [14]. The area can be also expressed in terms of bimedians as [16]. Bretschneider's formula [17] [14] expresses the area in terms of the sides and two opposite angles:.

Like all polygons that have more than three sides, quadrilaterals can be convex like these,or concave like these. Some K-8 curricula also include kites G and, in some definitions H.

A quadrilateral is a polygon having four sides, four angles, and four vertices. Shapes that do not have four sides or four angles or have curved sides or are open shapes are non-examples of quadrilaterals. There are many real-life quadrilateral examples: cards, chess boards, traffic signs, etc. Quadrilaterals can be classified into Parallelograms , Squares , Rectangles , and Rhombuses. Square, Rectangle, and Rhombus are also Parallelograms. A quadrilateral is called a concave quadrilateral if at least one diagonal, i. A quadrilateral is convex if the line segment joining any of its two vertices is in the same region.

Categorize quadrilaterals based on sides and angles. Identify them visually, and by description. Find lengths and angles, determine shapes, and prove congruence and if lines are parallel. Rasha is helping her father paint the door frame of their home. She calls out the names of each shape that she paints. She reaches a shape that she cannot name. She sees that it has four sides and one set of parallel sides. What shape is she painting? Polygons are closed shapes with sides made up of lines. Any closed shape with straight edges, such as a triangle or rectangle , is a polygon.

Polygon with 4 sides is called

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides or edges of a polygon are made of straight line segments connected end to end to form a closed shape. The point where two line segments meet is called vertex or corners, and subsequently, an angle is formed. If a polygon contains congruent sides, then that is called a regular polygon. The below figure shows several types of polygons. If all the sides and interior angles of the polygons are equal, they are known as regular polygons. The examples of regular polygons are square, rhombus, equilateral triangle, etc.

Coxeter and S. This is also a corollary to the parallelogram law applied in the Varignon parallelogram. 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. The base angles, angle X and angle Y, are four times the measure of Another area formula including the sides a , b , c , d is [16]. Wikimedia Commons Wikibooks. Bibcode : IJQC.. The bimedians of a quadrilateral are the line segments connecting the midpoints of the opposite sides. Some K-8 curricula also include kites G and, in some definitions H. S2CID In the following table it is listed if the diagonals in some of the most basic quadrilaterals bisect each other, if their diagonals are perpendicular , and if their diagonals have equal length.

In geometry a quadrilateral is a four-sided polygon , having four edges sides and four corners vertices.

Note 2: In a kite, one diagonal bisects the other. Simple quadrilaterals are either convex or concave. Shapes that do not have four sides or four angles or have curved sides or are open shapes are non-examples of quadrilaterals. Forum Geometricorum. The bimedians of a quadrilateral are the line segments connecting the midpoints of the opposite sides. Perimeter of Shapes. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral. A quadrilateral is called a concave quadrilateral if at least one diagonal, i. The names of many of these special quadrilaterals are also typically part of the elementary curriculum, though little else about the properties of these figures may be studied until high school.

Like all polygons that have more than three sides, quadrilaterals can be convex like these , , , or concave like these ,. The perimeter of a quadrilateral is the length of its boundary. This also means that a quadrilateral has exactly four vertices, and exactly four angles. What is the isosceles triangle theorem?
