Create an Equilateral Triangle
1) Use the Compass tool to create two circles with radius AB, one centered at A and one centered at B.
2) Use the Intersect tool to mark the point where the two circles intersect.
3) Use the Polygon tool to create your triangle. Be sure the first and last points you click are the same.
4) Use the Distance tool and Angle Measure tool to verify the triangle is equilateral and equiangular.
