1) Using the COMPASS Tool, select B then A to create another circle with a radius of AB. move that new circle to center on point B.[br]2) The two circles will intersect twice. Pick one of those intersection points and label it C.[br]3) Repeat the same as step 1 creating a new circle with the radius AB but now centered on point C[br]4) Work your way around the circle, creating new intersection points D, E, F, G all being created with the same compass circle with a radius of AB.. [br]5) You now have points B, C, D, E, F, G around the circle. Connect EVERY OTHER adjacent point to each other to create an equilateral triangle inside the circle.
