Delmar is constructing an equilateral triangle. he uses his straightedge to draw a segment and labels the endpoints w and x. with the compass opening equal to the length of the segment, he draws a circle centered at point w and then a circle centered at point x. he labels the intersections of the circles as points p and q. how should delmar finish the construction? use a straightedge to join points w and p and then points p and x. △wpx△wpx is equilateral. use a straightedge to join points p and q. label the intersection of pq¯¯¯¯¯pq¯ and wx¯¯¯¯¯¯wx¯ as a. construct the midpoint of ax¯¯¯¯¯ax¯ and label it b. use a straightedge to join points q and b. △qab△qab is equilateral. use a straightedge to join points w and p, p and q, and then w and q. △wpq△wpq is equilateral. use a straightedge to join points p and q. label the intersection of pq¯¯¯¯¯pq¯ and wx¯¯¯¯¯¯wx¯ as a. use a straightedge to join points q and x. △qax△qax is equilateral.
