Names and uses of different geometry box items
To draw different types of geometric figures, instruments like geometric tools are used. Geometry is one topic that has served the best even to the mathematics-haters because it is a place where one can score marks easily. On the other hand, it is one of the crucial topics, where we learn about different shapes of objects. To draw these shapes, we use different tools that are available in the geometry box. The geometry box items will also help you to solve problems and sketch plans on your own. We come across different shapes of objects in our daily life. Some of the shapes are squares, triangle, circle, hexagon, pentagon, parallelogram and so on. Not all the shapes have the same length, breadth, and height and this makes them fall apart from each other. Euclidean geometry or practical geometry is the most important branch of geometry that deals with the development of different geometrical figures using geometric instruments like a ruler, protractor, compass, divider, etc. This section will explain the different instruments of the geometry box, their uses, and description.
Geometry box items and uses:
Certain geometers like points, angles and lines mostly require the use of rulers and compass only. When the usage of different geometric shapes increased, different geometric tools were invented. Some of the commonly available geometry box items are the following:
- Set squares
The ruler: Ruler which is also known as the straightedge is mostly used to construct or draw lines and measure the length of the line segment. Initially, the rulers were used only to draw straight lines but later for our convenience, the rulers were segmented into centimeters on one side and inch on the other side which is made useful for measuring purposes also.
The compasses: Compasses have two legs which are sharp at one edge and the other side is for holding the pencil. The distance between the sharp edge and the pencil is adjustable with the help of a screw available at the top of the compass. The compasses are used to trace arcs, draw circles, and mark angles.
The protractor: It is a semi-circle disk which is used to measure and mark the angles. It has a 0 to 180 degree marking that is used to mark or measure the angles within that range directly. It has the 0 to 180 degree marked from left to right and vice-versa.
The divider: The divider is similar to that of the compass but the difference is divider has sharp edges on both sides. They are used to measure and compare the differences between the two lengths.
The set-squares: They are triangular with some portion in between them being removed. There are two types of set squares one which has 45 and 90-degree angles and the other having 30, 60, and 90-degree angles. These set-squares are most commonly used for drawing parallel and perpendicular lines.
Like the different geometry box items, some geometry box contains the correction pen that is used to clear the mistakes that are made by pen. This correction pen was widely accepted by students as they found them to be very useful in their routine.
