Follow these steps to construct an equilateral triangle inscribed in a circle.
1) Using the POINT TOOL & SEGMENT TOOL, label point C on circle A to create diameter CB.
2) Using the COMPASS TOOL, create a circle with radius AB and center point B
3) Using the POINT TOOL, mark points D and F where circle A intersects circle B.
4) Using the SEGMENT TOOL, draw a segment from point D to point F.
5) Using the SEGMENT TOOL, draw a segment from point D to point C.
RESULT: Equilateral triangle DCF inscribed in circle A.
