Planes and many other basics of geometry are often credited to the Greek mathematician Euclid , who lived around the year B. Euclid developed the idea of a plane , along with other fundamental concepts of geometry, such as points, lines, and two-dimensional shapes. All two-dimensional geometry exists on a plane. Because of this, geometry that deals with two-dimensional shapes is called plane geometry.

The other major type of geometry is solid geometry , which involves three-dimensional space and shapes, such as cubes and cylinders. We encounter planes all the time in everyday life, even though we might not use geometric terms to describe them. Should I continue studying statistics or should I study plane geometry?
