A circle is a simple shape in Euclidean geometry.

In mathematics, convex geometry is the branch of geometry studying convex sets, mainly in Euclidean space.

Now, in geometry, (and what we'll be doing is Euclidean geometry) this is really what math is about.

Before hyperbolic geometry, mathematicians knew about two kinds of space Euclidean space, and spherical space.

The discovery of hyperbolic space ushered in the field of mathematics that is called non Euclidean geometry.

Set Euclidean Coordinate System

Albert Einstein used non Euclidean geometry as well to describe how space time becomes warped in the presence of matter, as part of his general theory of relativity.

But before Descartes is generally viewed. that geometry was euclidean geometry. and that's essentially the geometry that you studied in geometry class in 8th or 9th or 10th grade. in a traditional high school curriculum. and that's the geometry of studying the relationships between triangles, and their angles. and the relationships between circles. and you have radii and then you have triangles inscribed in circles and all the rest and we'll go into some depth in that in the geometry playlist.

Euclidean space, and spherical space.

It's a definition really of Euclidean space.

So I found myself, in other words, constructing a geometry, a geometry of things which had no geometry.

These geometries became collectively known as non Euclidean geometries.

And here we're dealing with a two dimensional Euclidean space.

Geometry was a nightmare.

And what he did in those thirteen volumes was a rigorous, thoughtful, logical march through geometry, number theory and solid geometry (geometry in three dimensions).

The geometry of the screen

little bit hairy solid geometry.

Extract geometry from the images.

All the geometry is done.

It's a bit like this imagine that we'd only ever encountered Euclidean space.

He is well versed in geometry.

So when someone's talking about Geometry,

So basic starting point from Geometry

Navigating our planet requires elliptical geometry while the much of the art of M.C. Escher displays hyperbolic geometry.

You all have a sense of what a flat space is, Euclidean space is.
