RBSE Class 6 Maths Chapter 14 Notes Practical Geometry

→ The necessary tools/instruments for construction of geometrical figures :

• Rooler/Scale,
• Compass,
• Divider,
• Set square,
• Protector.

Many constructions can be done by these instruments.

→ We should be careful about the following points, while construction by scale and compass:

• Draw thin lines and mark light point.
• Always use sharp and thin instruments.
• Always keep two pencils in your box. One for compass and other for drawing line or curve or point.

→ We can draw the following geometrical shapes by using scale and compass :

• Circle, when radius is given.
• Line segment when length is given.
• Line segment of equal length to another, line segment.
• Draw a perpendicular from a point when
  • it lies on line
  • does not lie on line.
• Perpendicular bisector of a given line.
• Angle of given measurement.
• Angle of same measurement of given angle.
• Angle bisector.
• Some particular angles, like :
  (a) 60°
  (b) 30°
  (c) 120°
  (d) 90°
  (e) 45°
  (f) 135°.
