Regular HexagonsA regular polygon has equal sides and equal angles Let’s look at some examples A regular Pentagon (5 sides) A regular Hexagon (6 sides) How do we construct a regular pentagon (5-sided figure) and a regular hexagon (6-sided figure)? We need Length of each side Angle between two sides Let’s look into Regular Hexagon in Detail Regular Hexagon The formula for Angle made at center for Regular polygon is Angle at center = (𝟑𝟔𝟎° )/(𝑵𝒖𝒎𝒃𝒆𝒓 𝒐𝒇 𝒔𝒊𝒅𝒆𝒔) For Hexagon Angle at center = (360° )/6 = 60° Thus, our figure looks like Also, All these small triangles have same sides So, they are equilateral triangle Thus, all angles are 60° Now, let’s learn how to construct 60° angle
