How would I go about rotating a triangle 60 degrees using only a compass and straightedge!!!! I know how to rotate a triangle with a protractor and straight edge but this is not the same thing.
A 60 degree angle is one angle in an equilateral triangle. Set one leg of your compasses at the vertex about which you want to rotate. open it to the other end of that side and strike an arc with that side as radius. move your compasses to the other end of that side and strike an arc with the length of that side as radius. The point where the two arcs intersect is the third vertex of an equilateral triangle. A line segment from the initial vertex to that point where the two arcs intersect is that initial side rotated by 60 degrees. Now, copy the initial triangle using that line segment as a side.
