What are the three classifications of polygons?

Concave polygons (at least one of the interior angles is greater than 180°) Convex polygons (all the interior angles are less than 180° Regular polygons (all the sides and angles measure the same) Irregular polygons (all the sides and angles measure different)

What are the 8 types of polygon?

A Polygon is classified based on its sides like a triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, and decagon according as it contains (3, 4, 5, 6, 7, 8, 9) and (10) sides, respectively.

What are the 15 polygons?

In geometry, a pentadecagon or pentakaidecagon or 15-gon is a fifteen-sided polygon.

What is a polygon explain the types with the help of examples?

An example of a polygon is a triangle with three sides. A circle is also a plane figure but it is not considered a polygon, because it is a curved shape and does not have sides or angles. Therefore, we can say, all the polygons are 2d shapes but not all the two-dimensional figures are polygons.

What are the examples of polygon?

Triangles, hexagons, pentagons, and quadrilaterals are all examples of polygons. The name gives an indication of how many sides the shape has. For example, a triangle consists of three sides while a quadrilateral consists of four sides.

What is a 20 sided polygon called?

The icosahedron – 20-sided polyhedron – is frequent. Most often each face of the die is inscribed with a number in Greek and/or Latin up to the number of faces on the polyhedron.

What is 100 sided polygon called?

A 100-sided polygon is called a hectogon, centagon or 100-gon.

What is a 99 sided polygon called?

What is a 99 sided shape called? In geometry, an enneacontagon or enenecontagon or 90-gon is a ninety-sided polygon. Thus, the 99 sided shape is called nonacontakainonagon or enneacontanonagon. Here, enneaconta is the prefix for the number of sides numbered from 90 to 99.

How many types of polygon are there?

There are 4 types of Polygon : Regular Polygon: If all the sides and interior angles of the polygon are equal or if a polygon is equiangular and equilateral, then the polygon will be known as a regular polygon. Example square, rhombus, equilateral triangle, etc.

Is any 3 sided polygon a triangle?

Triangles are polygons with three sides, so any polygon with three sides is called a triangle.

What is the classification of the polygons according to convexity?

Convex polygons

They are convex when the measure of all the internal angles are less than 180°, implying that the convexity is observed from the outside of the polygon.

How many Decagons are there?

Polygons: How Many Sides?
3triangle, trigon
9nonagon, enneagon

What is a 4 sided polygon called?

Definition: A quadrilateral is a polygon with 4 sides. A diagonal of a quadrilat- eral is a line segment whose end-points are opposite vertices of the quadrilateral.

What is a 4 sides shape called?

A quadrilateral is a 4 sided closed figure. These figures are quadrilaterals: A shape with four sides. The shape has one set of parallel sides and does not have any right angles.

What is a 5 sided shape called?

A pentagon is a shape with 5 sides and 5 angles. An octagon is a shape with 8 sides and 8 angles. A trapezoid is a quadrilateral with one set of parallel sides.

What is a 6 sided polygon called?

In geometry, a hexagon can be defined as a closed two-dimensional polygon with six sides. Hexagon has 6 vertices and 6 angles also. Hexa means six and gonia means angles.

What is a 7 sided shape 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 3 sided shape called?

Triangles. A triangle has 3 sides and 3 corners. A corner is where two lines meet or join. There are different kinds of triangles.

What is a 8 sided polygon called?

regular octagon shape
A regular octagon shape has eight equal sides and eight equal angles. All the sides are of equal length, and all the angles are of equal measure. The sum of the interior angles is 1080°, and the sum of the exterior angles is 360°. In a regular octagon, the interior angle at each vertex is 135°.

What is a 10 sided polygon called?

A decagon is a closed shape with ten sides and ten angles.
