A quadrilateral is formed by four line segments that intersect at their endpoints. This quadrilateral is named by its endpoints, WXYZ, like a triangle. … Polygons are figures that are formed by three or more line segments. These line segments, even called sides, meet at their endpoints to form vertices.
What's the difference between a quadrilateral and a regular polygon?
Quadrilateral: polygon with four sides. Regular polygon: polygon with any number of sides but all sides must be equal in length and all interior angles must have equal measure.

Is a polygon a square?
In non-Euclidean geometry, squares are more generally polygons with 4 equal sides and equal angles. In spherical geometry, a square is a polygon whose edges are great circle arcs of equal distance, which meet at equal angles.

What is a polygon with 4 equal sides?
Four-sided polygons are usually referred to as quadrilaterals, quadrangles or sometimes tetragons. In geometry the term quadrilateral is commonly used. … The internal angles of all quadrilaterals add up to 360°. Square: Four sides of equal length, four internal right angles.What is quadrilaterals shapes?
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.
What is a polygon shape?A polygon is a closed shape with straight sides. Rectangles, triangles, hexagons, and octagons are all examples of polygons. The word polygon comes from the Greeks, like most terms in geometry, which they invented. It simply means many (poly) angles (gon).
Article first time published onWhat are 4 Quadrilaterals?
A quadrilateral is a four-sided two-dimensional shape. The following 2D shapes are all quadrilaterals: square, rectangle, rhombus, trapezium, parallelogram and kite.
Is a circle a polygon?
A circle is not a polygon. … A polygon is a closed figure on a plane formed from a finite number of lines segments connected end-to-end. As a circle is curved, it cannot be formed from line segments, as thus does not fit the conditions needed to be a polygon.
Are polygons always rectangles?
A rectangle is only a regular polygon if it is also a square.
What is square diagonal?
The diagonal of a square is a line segment that joins any two non-adjacent vertices. A square has two diagonals that are equal in length and bisect each other at right angles. The diagonal of square formula is used to calculate the length of the diagonal of a square when its side length is known.

What is the diagonal of Pentagon?
Therefore, the number of diagonals in a polygon pentagon is 5.
Can polygons be concave?
A concave polygon is a polygon that is not convex. … An example of a non-simple (self-intersecting) polygon is a star polygon. A concave polygon must have at least four sides.
What shape is a octagon?
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} and can also be constructed as a quasiregular truncated square, t{4}, which alternates two types of edges. A truncated octagon, t{8} is a hexadecagon, {16}.
What is a star shape called?
Regular star shape: A regular star shape, also known as a regular star polygon, is a self-intersecting equilateral and equiangular polygon.

What are polygons and vertices?
The segments of a polygonal circuit are called its edges or sides. The points where two edges meet are the polygon’s vertices (singular: vertex) or corners. The interior of a solid polygon is sometimes called its body.
How many quadrilaterals are there?
There are 5 types of quadrilaterals – Rectangle, Square, Parallelogram, Trapezium or Trapezoid, and Rhombus.
What are pentagon shapes?
A pentagon shape is a flat shape or a flat (two-dimensional) 5-sided geometric shape. In geometry, it is considered as a is a five-sided polygon with five straight sides and five interior angles, which add up to 540°.
What is quadrilateral example?
A quadrilateral is a closed two-dimensional figure that has 4 sides, 4 angles, and 4 vertices. A few examples of quadrilaterals are square, rectangle and trapezium.
What is called quadrilateral?
A quadrilateral is a four-sided polygon, like a square, rectangle, or rhombus. … The most common type of quadrilateral is the square, but rectangles and rhombuses are quadrilaterals too. Quadrilaterals are also called quadrangles and tetragons. When you see the word quadrilateral, think “four sides”.
What polygon has 9 sides?
A nine-sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners, or vertices. The word “nonagon” comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.
What is a polygon with 12 sides called?
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
What is a shape with 7 sides called?
A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning “seven”) with the Greek suffix -gon (from gonia, meaning “angle”), and is therefore not recommended.
What is a polygon for kids?
Any closed two-dimensional shape with three or more sides is called a polygon. Triangles and squares are polygons, as well as more complicated shapes like a twelve-sided dodecagon. … The sides and angles of a regular polygon are all equal. An irregular polygon has at least two sides or two angles that are different.
What are polygons for grade 2?
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is “closed” (all the lines connect up).
What is a polygon in math definition?
polygon, In geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides). … A polygon with all sides equal is equilateral.
