Math Names of Polygons

In this article we see about some names of each polygon in math, three sided polygon is triangle, some 4 sided polygons are square, rectangle, rhombus, parallelogram, trapezoid and quadrilateral. Each polygons have several properties. In math a closed geometric figure with three or more sides are also called polygon. Polygons have regular and irregular polygons shapes.

Math names of polygons:


Three sided polygons in math:
In 3-sided polygon the total angle of a triangle is 180 degrees.   
                                    3 sided polygon triangle
The triangle consists of many names in math:
• Right triangle
• Acute triangle
• Obtuse triangle
• Equilateral triangle
• Isosceles triangle
• Scalene triangle
Names of special polygons in math with 4 sides:
                                           4 sided polygon
• In math 4-sided polygons, the total angle of a quadrilateral is 360 degrees.
• In math 4-sided polygon having all right angles. The total angle of a rectangle is 360 degrees.
• In math 4-sided polygon having equal length for all sides meeting at right angles. The total angle of a square is 360 degrees.

• In math 4-sided polygon have two pairs of parallel sides. The total angle of a parallelogram is 360 degrees.
• In math 4-sided polygon having all four sides of equal length. The total angle of a rhombus is 360 degrees.
• In math 4-sided polygon having accurately one pair of parallel sides. The two sides that are parallel in trapezoid are called the bases. The total angle of a trapezoid is 360 degrees.
Some 3d polygons in math are
Cube, pyramid, cone etc

Math names of other polygons with many sides:


Regular and Irregular polygons with many sides:
• Regular polygon – all angles are equal and all sides are the same length. Regular polygons have both equiangular and equilateral.
• Equiangular – all the angles are equal
• Equilateral – all the sides are same length
• Irregular polygon –A polygon whose all sides are not the same length or whose interior angles do not all have the same measure.
• Convex polygon – you can draw a straight line through a convex polygon crosses at most two sides. Every interior angle is less than 180 degree.
• Concave polygon –You can draw at least one straight line through a concave polygon that crosses more than two sides. At least one interior angles is more than 180 degree.


Other polygons:
If a figure contains 5 sides, then the name of the polygon is Pentagon
If a figure contains 6 sides, then the name of the polygon is Hexagon
If a figure contains 7 sides, then the name of the polygon is Heptagon
If a figure contains 8 sides, then the name of the polygon is Octagon
If a figure contains 9 sides, then the name of the polygon is Nonagon
If a figure contains 10 sides, then the name of the polygon is Decagon
If a figure contains 12 sides, then the name of the polygon is Dodecagon
