1. What is the Interior Angle Calculator?

The Interior Angle Calculator computes the measure of each interior angle in a regular polygon. For triangles, it calculates the equal angles in an equilateral triangle using the standard polygon interior angle formula.

2. How Does the Calculator Work?

The calculator uses the interior angle formula:

Where:

• \( n \) — Number of sides in the polygon

Explanation: The formula calculates the measure of each interior angle in a regular polygon by dividing the total sum of interior angles by the number of sides.

3. Importance of Interior Angle Calculation

Details: Calculating interior angles is essential in geometry for understanding polygon properties, architectural design, and various engineering applications.

4. Using the Calculator

Tips: Enter the number of sides (must be 3 or greater). For triangles, enter 3 to calculate the interior angle of an equilateral triangle.

5. Frequently Asked Questions (FAQ)

Q1: What is the interior angle of an equilateral triangle?
A: Each interior angle of an equilateral triangle measures 60°.

Q2: Can this calculator be used for irregular polygons?
A: No, this calculator is designed for regular polygons where all sides and angles are equal.

Q3: What is the maximum number of sides I can calculate?
A: There's no theoretical maximum, but extremely large numbers may not represent practical geometric shapes.

Q4: How accurate are the results?
A: The results are mathematically precise based on the formula, rounded to one decimal place for readability.

Q5: Can I use this for triangles other than equilateral?
A: This calculator assumes regular polygons. For scalene or isosceles triangles, different calculations are needed.
