1800-102-2727Chapter 18- Basic Geometric tools explain the importance of these tools, which are essential to draw the basic shapes of geometry. The properties of shapes can be identified theoretically. However, the construction of shapes in practice is necessary. This chapter completely deals with the introduction of basic geometric tools. It focuses on a few methods to construct simple shapes based on the requirements. For example, angles considered an essential part of a shape can be drawn with the help of a set square. Place the required angle using a Set Square and draw two rays along the edges from the vertex of the placed set square.
Chapter 18- Basic Geometric tools, explains the procedure to construct and identify angles. Angles can be identified using a protractor that has markings from 0° to 180°. There are a few steps to be followed to measure the required angle using a protector. A ruler is a basic tool to draw a line and measure the line segment within the given range. Various units of measurement are provided. The lines between the numbers are known as "Hash Marks".
The chapter further talks about a ray that can also be constructed from a given line on the desired angle. Dividers are the most basic tools used to draw line segments with an accurate measure. It is used to mark the distances, and it is also capable of measuring the lengths.
The ending portion of the chapter contains an important discussion on a compass and a divider. There is a significant difference between a compass and a divider in practice. In the case of a compass, a sharp point and a holder hold the pencil. The divider has two sharp points, one point is placed at the centre, and the other is used to mark the given measurement.
