The sum of interior angles of a triangle is 180°, of a quadrilateral is 360°, of a Pentagon is 540°, find the sum of the interior angles of a dodecagon (12 sides)

Answer 1

To find the sum of the interior angles of a dodecagon, we can use the formula:

Sum of interior angles = (n - 2) * 180°

Where n is the number of sides of the polygon.

For a dodecagon (12 sides), the formula becomes:

Sum of interior angles = (12 - 2) * 180°

Sum of interior angles = 10 * 180°

Sum of interior angles = 1800°
