Software for drawing geometry diagrams

What software do you use to accurately draw geometry diagrams?


Solution 1:

For geometry I've always used Geogebra, and I think it's pretty good.

Solution 2:

Tikz is a nice LaTeX package for easily drawing diagrams. Diagrams are made by putting code directly into the TeX document, eliminating the need for extra image files. The package also is very powerful and versatile; the manual contains a very detailed description of its features.
