SCULPTURE A triangular entrance way has walls with corner angles of 50°, 70°, and 60°. The designer wants to place a tall bronze sculpture on a round pedestal in a central location equidistant from the three walls. How can the designer find where to place the sculpture?

• Find the circumcenter, where the three perpendicular bisectors meet.

• Find the incenter, where the three angle bisectors meet.

• Draw the perpendicular bisector of the longest side.

• Draw the angle bisector of the greatest angle.
