Apothem Calculator
What is an Apothem?
An apothem is a line segment that extends from the center of a regular polygon perpendicular to any of its sides, forming a right angle. It is also known as the shortest distance from the center to any side of the regular polygon. The apothem is crucial in calculating the area of regular polygons and is an essential concept in geometry. In regular polygons, all apothems are equal in length due to the polygon’s symmetrical properties.
How to Use Apothem Calculator
Step 1: Enter the number of sides for your regular polygon (must be 3 or greater) in the “Number of Sides” field.
Step 2: Input the length of one side of your regular polygon in the “Side Length” field.
Step 3: Click the calculate button to generate comprehensive results.
Step 4: Review the calculated results, which include:
- Apothem length
- Total area of the polygon
- Perimeter measurement
- Interior angle value
- Circumradius length
Step 5: Examine the calculation details provided below the results to understand how each value was determined using geometric formulas.
Step 6: For different calculations, simply modify the input values and calculate again. The calculator will automatically update all measurements and provide new explanations.
