As you should be able to tell from the title – but let me just confirm it – this really is a book all about triangles. Do not buy it if you are not remotely interested in these shapes with three sides! But if you like popular science books, are intrigued by the shapes that make up the universe, don’t mind a little mathematics in your reading, or are actually a triangles-big-time-fan, then this book could be for you.

As for me, I like dabbling in a bit of popular science-type reading, but I’m not a mathematician or anywhere near it.

Essentially, the book explores all the ways triangles are used or can be found in the world, with plenty of illustrations and examples to go with it. The writing style is fun and engaging and you can learn a lot! The slight downside to me is that I didn’t really find a narrative thread to follow, it was simply interesting a few pages at a time. So I’d read a section and then come back to it later, but there was no desperate urge to read more right away. Saying that, I think that can work well for a non-fiction book. I read it on Kindle, but I think it would be best in physical form where you can leave it somewhere handy and then pick it up for a short read now and then.

Plus, if you know anyone into maths/science/triangles, this would be an awesome gift.
