Polygon (Various Sides) Area and Dimensions Calculators

Overview:

Polygon is a two-dimensional geometric shape of straight line segments connected end to end, forming a closed figure. These segments are called sides or edges, and the points where they meet are called vertices. Polygons are classified based on the number of sides they have, such as triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), and so on. Polygons can be regular, with all sides and angles equal, or irregular, where sides and angles may vary. They are widely used in geometry, design, and architecture.

Calculator for Area and Inscribed Radius of a Polygon (Various Sides)

Instructions:

  1. Enter all but one value in available calculator fields. refer to diagram for value definition.
  2. Choose the units you would like to use default value is meters (m).
  3. Choose how many decimal places you wish answer to round to, the default value is one.
  4. Press solve button to find remaining unknown value.
  5. To perform a new calculation or you wish to clear current values use the reset button to clear values and start again.
  6. The formulas used for each calculator can be viewed by expanding the 'Click to Show Formula' section below.
