One day, Descartes noticed a fly crawling around on the ceiling. When he got out of bed, Descartes wrote down what he had discovered. Then he tried describing the positions of points, the same way he described the position of the fly. Descartes had invented the coordinate plane!

## What is the history of coordinate geometry?

History. The method of describing the location of points in this way was proposed by the French mathematician René Descartes (1596 – 1650). (Pronounced “day CART”). He proposed further that curves and lines could be described by equations using this technique, thus being the first to link algebra and geometry.

## Why is it called Cartesian coordinate system?

The Cartesian coordinate system is used to plot points. The Cartesian plane is named after the French mathematician and philosopher René Descartes (1596–1650), who introduced the coordinate system to show how algebra could be used to solve geometric problems.

## What is basic of geometry?

Basic geometry is the study of points, lines, angles, surfaces, and solids. We put two points in order to name the line as line AF. However, there are an infinite amount of points. You can also name it line FA. Line segment: A line segment is part of a line.

## Is 7th grade harder than 8th?

Seventh grade is a little bit easier than 8th grade because is more of an introduction into middle school, so they aren’t required to do as much work as 8th graders. The 8th graders are preparing for high school, so we have to do more to be ready for all of the work that high school will make us do.
