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 respectively, so it 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.

Polygon with 4 sides is called

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.

Shape: Equiangular Read more. This figure has side lengths of 1, 2, 3, and 4 respectively, so it is an irregular quadrilateral. 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". 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].

Wiki User. A polygon with 3 sides is called triangle A polygon with 4 sides is called quadrilateral A polygon with 5 sides is called pentagon A polygon with 6 sides is called hexagon A polygon with 7 sides is called heptagon A polygon with 8 sides is called octagon. A polygon may have any number of sides. A shape with four sides is a type of polygon called a quadrilateral. A polygon whose sides are not equal is known as an irregular polygon.

In geometry a quadrilateral is a four-sided polygon , having four edges sides and four corners vertices. Of all convex quadrilaterals with given diagonals, the orthodiagonal quadrilateral has the largest area. Cyclic quadrilaterals: For some quadrilaterals, it is possible to pass a single circle through all four of its vertices. Is an equilateral triangle is sometimes, never or always an isosceles triangle? Polygon with four sides and four corners. Inclusive definitions are used throughout. The perimeter of a quadrilateral is the length of its boundary. 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. This article is about four-sided mathematical shapes. Wikimedia Commons has media related to Tetragons.

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.

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. It is also called a tetragon , derived from Greek "tetra" meaning "four" and "gon" meaning "corner" or "angle", in analogy to other polygons e. The quadrilateral with given side lengths that has the maximum area is the cyclic quadrilateral. It states that. 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. Coolidge, "A historically interesting formula for the area of a quadrilateral", American Mathematical Monthly , 46 — You can reuse this answer Creative Commons License. Then the "area centroid" is the intersection of the lines G a G c and G b G d. A quadrilateral is convex if the line segment joining any of its two vertices is in the same region.
