31. Inscribing an equilateral triangle in a circle. NO QUESTIONS ARE TO
BE ASKED FOR THIS PROBLEM. This is and exercise on following written
directions and “figuring things out.”
Method: Use the endpoints of a diameter to construct an equilateral triangle
inscribed in a circle.
Step 1: Use the given center and the straightedge to construct a diameter of
the circle. Use the compass to measure the radius.
Step 2: Using the radius of the circle, place the point of the compass at an
endpoint of the diameter, and make two arcs that intersect the circle at two
different points.
Step 3: Construct the sides of the equilateral triangle by connecting these two
points to the other endpoint of the diameter.
