 # Practical Geometry Class 6 Maths Notes - Chapter 14

Practical geometry is an important branch of geometry which deals with the study of the size, positions, shapes as well as dimensions of objects.

## Geometrical Instruments

Whether you have to draw a line segment or measure it, draw a circle or arcs, draw an angle, etc. it can easily be possible with the help of geometrical tools. Let us discuss the various geometrical instruments used in practical geometry.

 Name of Geometrical tool Use of Geometrical tool Ruler To measure lengths of the line segment and to draw a line segment Compass To draw circles, arcs, and to mark equal lengths Divider Comparing lengths Set Squares To draw parallel and perpendicular lines Protractor Measure as well as draw angles

### Practical Geometry Important Questions

1. Draw ∠XYZ of measure 70° also find its line of symmetry.
2. Draw a circle of radius 5.2 cm.
3. Can you draw the figure of a right angle and construct its bisector?
4. Draw an angle measuring 45° also bisect it.
5. Draw an angle measuring 153° also divide it into four equal parts.
6. Draw any line segment AB. Without measuring AB, construct a copy of AB.
7. Draw a circle with center C and radius 4.4 cm. Draw chord AB and construct
the perpendicular bisector of AB. Also. examine if it passes through C.
8. Draw an angle measuring 70°. Also, make a copy of it using compasses and a straight edge only.
9. Draw AB of length 6.3 cm also, find its axis of symmetry.
10. Draw a line segment PQ. Mark any point O on
it. Through O, draw a perpendicular to PQ. (note: use compasses and ruler only)
11. Construct angles with compasses and ruler only, for the following:
(a) 120° (b) 60° (c) 135°
