Step 1: Count the number of sides (n) in the polygon. Step 2: Apply the Interior Angle Sum Theorem formula: (n - 2) * 180 degrees to find the sum of interior angles. Step 3: Divide the sum of interior angles by the number of sides (n) to find the measure of each interior angle.
This free triangle calculator computes the edges, angles, area, height, perimeter, median, as well as other values and a diagram of the resulting triangle.

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) ?
To find the measure of an interior angle in a polygon, you can use the following formula: Interior Angle = (n-2) x 180 / n. In this formula, “n” represents the number of sides of the polygon. By substituting the value of “n” into the formula, you can calculate the measure of each interior angle.
