Math Definitions - Letter H


Definition of Hemisphere

Definition of Hemisphere

A hemisphere is half a sphere.

Because the Earth is roughly spherical in shape, we divide it up into hemispheres. The part of the Earth north of the equator is called the Northern Hemisphere. We live in the Southern Hemisphere (the part of the Earth that is south of the equator). The map in the picture is of the Southern Hemisphere.

The Earth can also be divided up into Eastern and Western Hemispheres. Australia lies in the Eastern Hemisphere.


The aim of this dictionary is to provide definitions to common mathematical terms. Students learn a new math skill every week at school, sometimes just before they start a new skill, if they want to look at what a specific term means, this is where this dictionary will become handy and a go-to guide for a student.
