Construction of Angles Constructing 30, 60, 90, 120 Degree Angles

Construction of Angles - In an equilateral triangle, all the angles are equal and they are equal to 60º in size. Thus, in order to draw 60º, we need to construct an equilateral triangle. 120º angle can be constructed using the logic that 60º + 120º = 180º. Thus, we can understand that in order to construct 120º we can construct 60º angle.
