A polygon is simply a shape ... It has four right angles (90°). The opposite sides are parallel. The diagonals bisect each other. The exterior angles of a rectangle are each 90°.

How would you work out the sum of internal angles in a polygon that has more than 4 sides? There is a formula that you can use to work out the sum of internal angles that works for all polygons ...

The exterior angles of a polygon always add up to 360°. Furthermore the interior and exterior angles at a point always add up to 180°. An exterior angle is the angle made with the side of the ...

The second method is to use the formula: sum of interior angles = (𝒏 – 2) × 180. This gives (10 – 2) × 180 = 1440 Image caption, Find the sum of the interior angles of a 26-sided polygon.

If the side of a triangle is extended, the angle formed outside the triangle is the exterior angle. \(g\) is the interior angle. \(h\) is the exterior angle. \(g + h = 180^\circ\) The interior ...
