paragraph_text: Compass and straightedge constructions
  
  There are many compass-and-straightedge constructions resulting in circles.
  
  The simplest and most basic is the construction given the centre of the circle and a point on the circle. Place the fixed leg of the compass on the centre point, the movable leg on the point on the circle and rotate the compass.
