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. This figure has side lengths of 1, 2, 3, and 4 polygon with 4 sides is called, so it is an irregular quadrilateral.

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].

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. The perimeter of a quadrilateral is the length of its boundary. This means the perimeter of a quadrilateral equals the sum of all the sides. The formula for the perimeter of some of the common quadrilaterals is given below:. The area of the quadrilateral is the region enclosed by all its sides. The formulas to find out the area of different types of quadrilaterals are shown below:. Example 1. Find the missing angle in the given quadrilateral. Example 2: What will be the perimeter of a quadrilateral with sides 6 cm, 8 cm, 10 cm, and 12 cm?

The classification schemes taught in elementary school involve the number of pairs of parallel sides, and the congruence of sides, and whether or not all the angles are right angles all angles are congruent.

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.

Quadrilateral A quadrilateral is a polygon that has exactly four sides. The base angles, angle X and angle Y, are four times the measure of In two-dimensional Euclidean space, expressing vector AC as a free vector in Cartesian space equal to x 1 , y 1 and BD as x 2 , y 2 , this can be rewritten as:. The area of the quadrilateral is then. Note 1: The most general trapezoids and isosceles trapezoids do not have perpendicular diagonals, but there are infinite numbers of non-similar trapezoids and isosceles trapezoids that do have perpendicular diagonals and are not any other named quadrilateral. Then E is the midpoint of OH. Washington, D. A hierarchical taxonomy of quadrilaterals is illustrated by the figure to the right. Some examples of quadrilaterals: 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 line is remarkable by the fact that it contains the area centroid. Another remarkable line in a convex non-parallelogram quadrilateral is the Newton line , which connects the midpoints of the diagonals, the segment connecting these points being bisected by the vertex centroid. From this inequality it follows that the point inside a quadrilateral that minimizes the sum of distances to the vertices is the intersection of the diagonals.

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".

Inclusive definitions are used throughout. Formulas to compute its dihedral angles from the edge lengths and the angle between two adjacent edges were derived for work on the properties of molecules such as cyclobutane that contain a "puckered" ring of four atoms. Then the "area centroid" is the intersection of the lines G a G c and G b G d. This also means that a quadrilateral has exactly four vertices, and exactly four angles. Example 1. Some types of quadrilaterals. Like all polygons that have more than three sides, quadrilaterals can be convex like these , , , or concave like these ,. In other projects. ISBN Polygon with four sides and four corners. A quadrilateral is a polygon having four sides, four angles, and four vertices. Some K-8 curricula also include kites G and, in some definitions H. 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. This may be accessible for middle grade students who have learned about perpendicular lines and bisectors. Retrieved 1 March
