Plato advocated the inclusion of mathematics in school curriculum because mathematics reasoning disciplined the mind. It is only subject that encourage and develops logical thinking, it enables the student to discriminate between essential and non essential, it helps them to understand the facts, to draw necessary conclusion etc. Except mother tongue there is no other subject which is more closely related to our daily life as mathematics. Geometry is an important branch of mathematics which dominates the learning of the mathematics in high school classes, whereas arithmetic and algebra both are science of numbers, geometry is science of lines and figures. It is concerned with concept of size, shape, relative position of figure and properties of space.
