Construct a 30 Degree Angle

New Review

Split it down the middle. Using the tools of geometric construction, the video shows two different methods of constructing a 30-degree angle. The first method bisects an angle of an equilateral triangle. The second uses the diagonal of a rhombus to bisect a 60-degree angle of the rhombus.
