sketchometry vs XSection

Fascinatingly simple. Simply fascinating. sketchometry is a different kind of dynamic math software. You draw with your finger on your iPhone or iPad. sketchometry automatically converts these (finger) sketches into exact geometric objects. Mathematics becomes an experimental subject. No ready-made results are presented, learners are encouraged to go on a journey of discovery by themselves.

Learn how to construct cross sections of polyhedrons. Study different techniques, train yourself, and then solve geometric puzzles. > 105 tasks: from basics to challenges > 12 subjects to explore > Step-by-step instructions > 35 geometric terms in a glossary > Night mode > Easy to use > Develops your spatial imagination *** About *** XSection is an introduction to solid geometry.
