When do you actually use geometry in life outside of school?

Answer 1

It is very important that we as a human race do not become too dependant upon computers to do everything for us to the point of that, if they quit working for us, we would be lost. Thus the reason for the seemingly mundane. Furthermore, geometry is more of a building block (no pun intended) in preperation for the higher mathematics such as algebra, trig, calc and differiential equations. All of these maths are used frequently by engineers in conjunction with the computer programs they use. Whether it be designing a road (civil), designing a drill chuck (mechanical) or creating a 3D structure of an atom (chemical) . . . when using computers, it always pays to put the same mathematical ideas upon paper in order to broaden the perspectives and understandings of what and how the engineer is trying to accomplish their goals.
