I’ve just asked myself ‘what is the optimal pitch for an A-frame roof in a location* that gets snow’?

I have never lived in a climate where this sort of snowfall is likely or possible. And I have never built a house….

…out of anything but paper.

I’ve just spent far too long googling ‘what type of triangle has two equal sides and angles’ and ‘how do you find the perimeter of an isosceles triangle?’ Maths 1 is so many years ago. And there’s a 50/50 chance I didn’t pay attention in that unit.

*Rotterdam, and the year would be pre modern climate change, ie 19th century or earlier, when the snowfall was far heavier than it is now, but also not as heavy as somewhere like… Stockholm.
