POLYGONS
Pentagon:
pentagon is a five-sided polygon with five straight sides and five interior angles that sum up to 540°
Just like any regular polygon, going around a pentagon completes one full circle, so the exterior angles are found by dividing 360° by the number of sides, in this case, 360°/5=72

Hexagon:
-
Like any regular polygon, to find the interior angle we use the formula (180n–360)/6=120
-
What is polygons:A polygon is a closed plane figure bounded by straight lines. ABCDE is a polygon with vertices A, B, C, D, E in that order.
Properties of Regular Convex Polygons: 360°/n is the measure of one exterior angle for a regular polygon with n sides.(n-2)×180°/n is the measure of one interior angle for a regular polygon with n sides.
Regular (convex) polygon:All the sides have equal length and the interior angles have equal size; and the vertices lie on a circle.
A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A shape with curved sides is not a polygon.

Complex Polygon:A complex polygon intersects itself! Many rules about polygons don't work when it is complex.
-
Simple Polygon:A simple polygon has only one boundary, and it doesn't cross over itself.
