Hexagon is a geometric shape. In Greek Hex means six and Gonia means angle. Hexagon has six sides and angles, and the total summation of its six angles is equal to 720°. In the regular hexagon, each of its angles equals to 120°, and if they aren't equal, it is an irregular hexagon. In a convex hexagon, none of its angles can be more than 180° unlike the concave hexagon when any of its internal angles are more than 180°.
