In order to construct a circle circumscribed to a triangle, you need to: - first, find the perpendicular bisector of two of the sides of the triangle; - the two perpendicular bisectors will intersect in a point (C) that will be the center of the circle; - point the compass in C and open it to the width of one of the points of the triangle (CJ or CK or CL); - draw the circle.
Hence, the correct answer is: D) <span>Construct the perpendicular bisector of JL.</span>
