We see a lot of objects with different shapes and sizes around us.
We have also learnt about different shapes and their names in the earlier classes.
It is easy to draw a rough figure of a geometrical shape.
But how do you think shapes of specific measurements get constructed?
For that matter, we use specific geometric tools.
Nowadays, a geometry box comes with all the geometrical tools necessary.
Let us now look at each of the tools in detail.
A rectangular tool with measurements on it.
The measurements are in centimetres, millimetres and inches.
To draw a line segment with exact measurements.
To measure lengths.
A tool with two ends.
There is a pencil on one end, while the other is a pointy end.
To construct line segments, figures and so on.
A tool similar to the compass.
Unlike the compass, it has two pointy ends.
To divide a line segment into many equal parts.
Two triangular tools.
One has the angles \(45^\circ\), \(45^\circ\), and \(90^\circ\) at its vertices, while the other has the angles \(60^\circ\), \(30^\circ\), and \(90^\circ\) at its vertices.
To draw both perpendicular, and parallel lines.
A semi-circular tool.
It has measurements from \(0^\circ\) up to \(180^\circ\).
To draw and measure angles.
