Question

has partially completed the construction, as shown below. what should be his next step in the construction? connect the arc markings to angle e to find another bisector use the compass to find the perpendicular bisector for side df. connect three arc markings to determine the vertices from the triangle. use the circumcenter to determine the center of the circle

Explanation:

The red - colored arc - like markings suggest that the perpendicular bisectors of the sides of the triangle are being constructed. After constructing the perpendicular bisectors of two sides, the next logical step is to construct the perpendicular bisector of the third side. In this case, the third side is DF.

Answer:

Use the compass to find the perpendicular bisector for side DF.
