Drawing a triangle

A compass can be used to draw a triangle.

Draw a triangle ABC with side lengths of 6 cm, 5 cm and 4 cm.
  1. First, draw one side of the triangle, or the line segment AB.
  2. Use the end points of the line segment (points A and B) as the central points of two circular arcs. Draw two circular arcs, the radii of which are the same length as the two remaining sides of the triangle.
  3. Connect the intersection point C of the two arcs to the endpoints of the line segment AB.
