@Optionparty Those can be pretty handy. Specially the really memorable 3 - 4 - 5 one.

I have used that in the past to build a perfect 90 degrees corner in a building. A good tape measure, some lumber or metal lengths, and you get a square angle no sweat.

@design_RG Matching up two diagonals of a square works well too.

@Optionparty I love geometry.

We can even apply angle bissection via arcs in a construction setting and get accurate results.

String and a nail, swing a big arc, doig again from other points, intersection is the point we need.

A rigid piece like a metal profile is nice too, avoiding the possible error by stretching in the string.
