Geometry – Class VI

Geometry tells us about the lines, angles, shapes and practical geometry is about the construction of these shapes

Tools to be used for construction

  1. The Ruler: – A ruler is a straight edge which we something call a scale. It is used to draw a line-segment and also to measure them.
  2. The Compass: – The compass has two ends-one is pointer and other is for the pencil. It is used to draw arcs and circles and also them to measure the line-segment.
  3. The Divider: – It is a pair of pointers on both the ends. It is used to compare the length of line and arcs.
  4. Set-Squares: – It is set of two triangular pieces: –
  • One is having 45^\circ ,45^\circ and 90^\circ angles at the corners. It is used to draw parallel and perpendicular lines.
  • Another is having 30^\circ ,60^\circ and 90^\circ at the corners. It is also used to draw parallel and perpendicular lines.

The Protector: – It is a semi-circle device which is divided into 180^\circ parts. It starts from the 0^\circ from the right-hand side and ends with the 180^\circ on the left-hand side. It is used to measure and draw angles.
