Amy is using a drawing program to complete a construction with which she is almost finished. which construction is she completing? a. an equilateral triangle inscribed in a circle b. a square inscribed in a circle c. a regular pentagon inscribed in a circle d. a regular hexagon inscribed in a circle

From this point, Amy could construct either an equilateral triangle or a regular hexagon. The triangle takes fewer steps to complete.

If Amy designates the (top and bottom) points of intersection of the circles as D and E, then her inscribed equilateral triangle would be ∆BDE. The appropriate choice is ...

... a. An equilateral triangle inscribed in a circle.

If Amy continues by drawing diameters DAF and EAG, then she can inscribe regular hexagon BGDCEF in circle A.
