Aaron is constructing a circle circumscribed about a triangle. he has partially completed the construction, as shown below. what should be his next step in the construction? (5 points) triangle def is shown with two sets of intersecting arc markings on either side of side ef. a line segment is drawn through eac 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 the vertices form the triangle use the intersection of the arcs to determine the center of the circle
