Access Class 6 Mathematics Chapter 14 - Practical Geometry

The methods for sketching geometrical forms are covered in this chapter.

  • To create shapes, we employ the following mathematical instruments:

  1. A graduated ruler:

  • Along one edge, a ruler graduated in centimetres (and sometimes into inches along the other edge).

  • It is used to draw and measure the line segments.

  1. The compass:

  • It is a pair of a pencil on one end and a pointer on the other.

  • It is used not to measure the equal lengths, but to mark them off.

  • Also, it is used to make circles and arcs.

  1. The divider: 

  • It is a pair of pointers.

  • It is used to compare the lengths.

  1. Set-squares: 

  • Set squares are the two triangular pieces, one with \[{{45}^{0}},{{45}^{0}}\] and \[{{90}^{0}}\] angles at the vertices and the other with \[{{30}^{0}},{{60}^{0}}\] and \[{{90}^{0}}\] angles.

  • It is used to draw the parallel and perpendicular lines.

  1. The protractor: 

  • It is used to measure the angles.

  • It is like a semi-circular scale with markings as angles.

  • The following constructions can be created with the ruler and compass:

  1. A circle can be drawn only when the length of its radius is known.

  2. A line segment can be drawn when its length is given.

  3. Same procedure follows for the line segment.

  4. A perpendicular to a line can be drawn through a point

  1. On the line

  2. Not on the line.

  1. The perpendicular bisector of a line segment of given length can be drawn.

  2. An angle can be drawn for a given measure.

  3. A copy of an angle.

  4. The bisector of a given angle.

  5. Some angles of special measures such as

  1. \[{{90}^{0}}\]

  2. \[{{45}^{0}}\]

  3. \[{{60}^{0}}\]

  4. \[{{30}^{0}}\]

  5. \[{{120}^{0}}\]

  6. \[{{135}^{0}}\]

Construction of a circle when its radius is known:

Step \[1\]:

Open the compass for the required radius.

Step \[2\]:

Mark a point with a sharp pencil to denote where the centre of the circle has to be. Name it as \[O\].

Step \[3\]:

Place the pointer of the compass on \[O\].

Step \[4\]:

Now, turn the compass slowly either in clockwise or anticlockwise direction such that the pencil traces the circle of required radius. Care must be taken to complete the movement at one go.

Construction of a circle

Construction of a line segment of a given length:

A better method would be to construct a line segment of a given length with a compass.

Draw a line for \[\text{3 cm}\] by using the following steps.

Step \[1\]:

Draw a line \[l\] and make a point \[A\] on line \[l\].


Step \[2\]:

Place the pointer of the compass at the zero mark of the ruler. Extend the other leg of the compass upto the 3 cm mark on the ruler.

Measure of length with compass

Step \[3\]:

Taking caution that the opening of the compass has not changed, place the pointer on \[A\] and swing an arc to cut \[l\] at \[B\].

Construction of arc

Step \[4\]:

\[\overline{AB}\] is a line segment of required length.

Line segment

Constructing a Copy of a Given Line Segment:

A better technique would be to construct a line segment with a ruler and compass.

Following steps show how to draw \[\overline{AB}\].

Step \[1\]:

Given \[\overline{AB}\] whose length is not known.

Line AB

Step \[2\]:

Fix the compass pointer on \[A\] and the pencil end on \[B\]. 

The distance between the two open legs of the instrument now gives the length of \[\overline{AB}\].

Length of AB

Step \[3\]:

Draw any line \[l\]. 

Choose a point \[C\] on \[l\]. 

Without changing the compass setting, place the pointer on \[C\].

Line l with point C

Step \[4\]:

Swing an arc that cuts \[l\] at a point, say, \[D\]. 

Now \[\overline{CD}\] is a copy of \[\overline{AB}\].

Line CD

Method of Ruler and Compass:

Step \[1\]:

Given a point \[P\] on a line \[l\].

Point P on line l

Step \[2\]:

With \[P\] as centre and a convenient radius, construct an arc intersecting the line \[l\] at two points \[A\] and \[B\].

Construction of an arc that intersects at Two points

Step \[3\]:

With \[A\] and \[B\] as centres and a radius greater than \[AP\] construct two arcs, which cut each other at \[Q\].

Two arcs at point Q

Step \[4\]:

Join \[PQ\]. 

Then \[\overline{PQ}\] is perpendicular to \[l\]. 

We write \[\overline{PQ}\bot l\]

Perpendicular line PQ

Constructing a Copy of an Angle of Unknown Measure:

We have to use only a straightedge and the compass for constructing an angle whose measure is unknown.

With the help of following steps, we can draw an unknown angle \[\angle A\]

Step \[1\]:

Draw a line \[l\] and choose a point \[P\] on it.

Line l with point P

Step \[2\]:

Place the compass at \[A\] and draw an arc to cut the rays of \[\angle A\] at \[B\] and \[C\].

Line l with point P

Step \[3\]:

Maintaining the same settings on the compass, draw an arc with \[P\] as centre, cutting \[l\] in \[Q\].

Arc from point P

Step \[4\]:

Set the compass to the length \[BC\] with the same radius.

Measure of distance BC

Step \[5\]:

Place the compass pointer at \[Q\] and draw the arc to cut the arc drawn earlier in \[R\].

Arc at Q

Step \[6\]:

Join \[PR\]. This gives us \[\angle P\] . It has the same measure as \[\angle A\] . 

This means \[\angle QPR\] has the same measure as \[\angle BAC\].

Angle QPR
