Geometry Compass Constructions

Introduction Geometry Compass Constructions:
               Geometric Compass is used to draw a circle with a given measurement of its radius and a line segment. We can also construct angles of given measures with the compass. There is a provision in the compass to insert a pencil. By using geometric compass we can construct various shapes and figures. In our day today life geometric constructions  plays an important role from that learn that the concept of geometry have begun from ancient times.The basic constructions using a compass are,
  • Constructions for a line perpendicular to a given line.
  • Constructions for  perpendicular bisector of a given line.
  • Construct Intersection points between circle and line or two circles
  • Construction of a circle.

Constructions for a Line Perpendicular to a Given Line at a Given Point on it by Compass in Geometry:
Constructions:
Step 1:Draw a straight line l. Place the metal point of the compass on P. With the pencil Point make two small arcs of equal radius on l to cut the line at A and B.
