Have you ever used a set square?

[MissVantaBlack]

Just musing...DD asked me for a new protractor today. I enquired as to whether the rest of her geometry set was okay, and she replied that she'd never used the two set squares. She's in Year 11.

Thinking about it, I don't remember using my set squares when I was at school either. I asked DH (maths, further maths A-levels) and he also hadn't!

So...have you ever used a set square? Would you know how to use one? And how many Olympic-sized swimming pools could we fill with all the unused set squares from our DC's geometry sets? 🙂

@SheWoreYellow ah I see! That does look like a pretty rubbish tool!

This is what I think of when I hear the words “set square”. I guess it’s like a protractor, but in a triangle? Weird that different countries have slightly different tools for the same thing!

Log tables! There's a skill that was absolutely worthless as a life skill beyond 13.

I use one fairly regularly in work.

I work as a textile designer.

Vague memories of possibly using one in technical drawing.

Used them for isometric projections for technical drawing in CDT. Haven't used them much (except as short rulers) in the nearly 40 years since!

I do use small metal engineers squares from time to time for DIY jobs.

Never used one - and I did maths and further maths A Levels.

Yep, in graphics

Me too! (Love the username)

I used mine as a ruler when mine had broken or I couldn't be bothered getting it out of my bag (at school). Not used one as an adult.

I’ve only used them for design in the past, such as for isometric and axonometric drawings.

I remember being shown how to use one to draw parallell lines, in the 1980s, but only because one of my classmates asked what it was for.
Geometry sets are a waste of money and plastic. Much better to just buy a good quality proteactor and set of compasses.

Thanks everybody. Interesting that your set square is so different, @CrimsonAlligator !
