subject: Geometry Formats [print this page] Introduction to Geometry format: Introduction to Geometry format:
In geometry format has a most important part in the mathematics. Geometry provides the idea of various geometrical shapes and figures in our daily life such as articles in the houses, wells, buildings, bridges etc. From this we learn that the concept of geometry have begun from ancient times. The term Geometry means a study of properties of figures and shapes and the relationship between them.
We can Use Following Tools while Drawing a Geometry Format:
A Geometrical instruments box is a basic requirement for those who learn geometry format.
Compass: In Geometry format tools Compass is used to draw a circle with a given measurement of its radius and a line segment. We can also construct angles of given measures with the compass. There is a provision in the compass to insert a pencil.
Ruler: Let us recall their names and uses. One edge of the ruler is graduated in centimeters and the other in inches. A ruler is used to draw lines and measure the length of the line segment.
Divider: In Geometric tools It is used to measure the length of a line segment and to compare the lengths of two given line segments.
A pair of Set Squares: In Geometric tools they are used to construct perpendicular lines and parallel lines. One set-square has 30 60 90 angles at the vertices' and the other has 45 45 90 angles at the vertices'
In Geometry format a protractors curved edge is graduated into 180 equal parts. Each part is equal to one degree. The graduation starts from 0 on the right hand side and ends with 180 on the left hand side and vice-versa. A protractor is used to construct and to measure given angles 175.
In Geometric tools to construct almost accurate figures remember the following:
(a) In the Geometric tools box all the instruments should have fine edges and tips.
(b) It is better to have an eraser and two pencils in the box, to use one pencil with compass for inserting in it and the other to draw lines and mark points.
(c) Always draw thin lines and mark points lightly.
