Advanced Polygon Calculator. You can use this Advanced Polygon Calculator to calculate interior/exterior angle, inradius, circumradius, perimeter, area, and more. How to use the calculator: Simply select the units of measurement, enter the number of sides, specify the side length of a regular polygon, and let our calculator do the rest.
Here we will learn about interior angles in polygons including how to calculate the sum of interior angles for a polygon, single interior angles and use this knowledge to solve problems. There are also angles in polygons worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
The calculator will instantly provide results based on your input. This will include the missing side lengths, angles, perimeter, and area. What Is a Triangle? A triangle is a three-sided polygon. It is defined by its three straight sides and three internal angles. These angles always sum up to 180 degrees, regardless of the triangle's shape or ...

The General Rule. Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total: So the general rule is: Sum of Interior Angles = (n −2) × 180 °. Each Angle (of a Regular Polygon) = (n −2) × 180 ° / n. Perhaps an example will help: Example: What about a Regular Decagon (10 sides) ?
We can calculate the sum of the interior angles of a polygon by subtracting 2 from the number of sides and then multiplying by 180º. Step-by-step guide: Interior angles of a polygon. Exterior angles are the angles between a polygon and the extended line from the next side. The sum of the exterior angles of a polygon is always equal to 360º.
