With that said I I will admit I couldn’t tell you off the top of my head what trigonometry actually is.
It’s the study of the geometry of triangles (trigon - three-sided polygon + metry - roughly measurement of, with an extra o to join them together). You can use the basic principles of some parts of it to make life easier.
For example, the “3-4-5 rule”, based on the Pythagorean Theorem. If you need to make sure that something is roughly a 90° angle measure 3 units up one side and mark it, 4 units up the other and mark it, then measure the distance between the marks. If it is 5 units, then you have a 90° angle. The super cool thing is that you can use any unit used to measure linear distance; inches, angstroms, furlongs, kilometers, beard-seconds, whatever.

ooooh ok! interesting, good to know thanks
You’re welcome! It’s a super cool trick that an electrician taught me years ago.
must’ve been a shock
A bit but I quickly understood its potential.
