Knowing the difference between regular and irregular polygons can help when working out the size of missing angles. In order to work out the size of missing interior angles in polygons ...

This fact is a more specific example of the equation for calculating the sum of the interior angles of a polygon: \(\text {Sum of interior angles = (n – 2)} ~\times~180^\circ\) where \(\text{n}\) ...

Interior angle in a regular polygon = \(\mathbf{\frac{180(n-2)}{n}}\) If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle. The sum of the exterior ...

If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into triangles. The sum of interior ...

If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into triangles. The sum of interior ...

If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into triangles. The sum of interior ...

Interior angles in a triangle add up to 180˚. Triangles close triangleA polygon with three straight sides. have three sides, therefore they have three angles. Interior angles in a triangle sum to ...

If the angles are all equal and all the sides are equal length it is a regular polygon. To find the sum of interior angles in a polygon divide the polygon into triangles. The sum of interior ...

If the angles are all equal, and all the sides are equal in length, it is a regular polygon. To find the sum of interior angles in a polygon, divide the polygon into triangles. The sum of interior ...

You can always identify the polygon by how many sides it has. For example a pentagon ... of the equal sides are equal. The angles inside a shape are called interior angles. The interior angles ...
