I need a software to draw simple geometry things like this:
or even better:
Do you know any software capable to draw these things easily? Extra points if it works on Linux

Powerpoint or sketchup....
GeoGebra , it comes in multiple languages, it's easy to use, but powerful, it can be exported to LaTeX, SVG and other formats, it supports applets and other tools .
It's free, cross platform and open source.
You could try C.a.R.

Having some Geometry data and a Transform how can the transform be applied to the Geometry to get a new Geometry with it's data transformed ?
Ex: I Have a Path object that has it's Path.Data set to a PathGeometry object, I want to tranform the points ...

One catch is that Combine only works if....
You can scan the PathGeometry list of figures and segments .
There are two things you have to consider:
Geometry inherits from Freezable, you can't modify the geometry object in-place if it's frozen.

You should be able to do-PlaneIntersection.html
From my "Geometry" class:
public struct Line { public static Line Empty; private PointF enum Intersection....
So this is basic 3-D geometry.
If it's 2-D, then all lines are on the only plane .

What's the difference between mesh and geometry? Aren't they the same? i.e. collection of vertices that form triangles?

A curve is geometry....
A point is geometry, but it is not a mesh.
From Wikipedia :
Geometry and with properties of space
IMO a mesh falls under that criteria.
A mesh is simply a more complex shape.
Or a mixture of various polygons.
