The branch of mathematics concerned with properties of spatial measurements . This includes distance, shape, size, and even theoretical dimensional spaces higher than 3D. A mathematician who specializes in geometry is known as a geometer.
Euclidean geometry, the study of flat surfaces and spatial measurements surrounding them, began in Ancient Greece with the likes of Pythagoras, Archimedes, and Euclid. Euclid developed five basic postulates, the fifth being the famed "Parallel Postulate".
The parallel postulate is not provable as a theorem. This led to a lot of geometry branches that ignore the postulate entirely. The most famous of these non-Euclidean geometries is hyperbolic geometry.
There are other branches of geometry that are still in their infancy. One of these is fractal geometry, the branch of geometry concerned with fractals, shapes whose Hausdorff dimension is much greater than their topological dimension.
As you can see, geometry is an extremely broad branch of mathematics, with many different branches.

Ptolemy's Theorem details a very important relationship between diagonals and opposite sides of a cyclic quadrilateral in Euclidean geometry.

An ubran haircut; usually short where your shape ups in the front and back are sharp thus resembling geometry.

Something involving shapes almost pointless. It's a 9th grade course, but most kindergardeners can figure out how to do it.

1-the most terrible class ever invented. 2-a great wayy to fuck up your GPA
3-another way for teachers to make you feel like an even bigger dumbass then you really are
4-the most pointless form of math ever invented!

the most pointless form of math ever devised. it involves shapes, planes, and lots of proofs. has no real use, although teachers like to say it does. is no help to anyone.
torture.
torture.
geometry class is just another chance to take a 55-minute nap, and fail the class because your chances of understand and excelling at it are nearly zero.
