Two of the most common right triangles are 30-60-90 and the 45-45-90 degree triangles.All 30-60-90 triangles, have sides with the same basic ratio.If you look at the 30–60–90-degree triangle in radians, it translates to the following: This is a great (much needed) review tutorial. Again, line up the 60-degree marking with the bottom of the strip, and adjust your ruler so that the cut will make a precise point at the top. This construction works by creating an The missing angle must, therefore, be 60 degrees, which makes this a 30-60-90 triangle. It is exactly 1/6th of a circle.

And because this is a 30-60-90 triangle, and we were told that the shortest side is 8, the hypotenuse must be 16 and the missing side must be $8 * √3$, or $8√3$. The 30 – 60 – 90 degree triangle is in the shape of half an equilateral triangle, cut straight down the middle along its altitude. And because this is a 30-60-90 triangle, and we were told that the shortest side is 8, the hypotenuse must be 16 and the missing side must be 8 * √3, or 8√3. Place the point of the compass at the 60° angle's vertex. each side of the triangle should measure the same. I have a good size 60* triangle ruler but I am trying to puzzle out how to do a star without appliqueing it on. Using the other 60 degree line, line it up along the bottom also.
