Explore the life-changing magic of trigonometry with Matt Parker, stand-up mathematician and No. 1 bestselling author of Humble Pi
Why can no two people ever see the same rainbow? What happens when you pull a pop song apart into pure sine waves and play it back on a piano? Why does the wake behind a duck always form an angle of exactly 39 degrees? And what did mathematicians have to do with the great pig stampede of 2012? The answer to each of these questions can be found in the triangle.
In Love Triangle, stand-up comedian, ex-maths teacher and Sunday Times number one bestselling author Matt Parker is on a mission to prove why we should all show a lot more love for triangles, along with the useful trigonometry and geometry they enable. To make his point, he uses triangles to create his own digital avatar, survive a harrowing motorcycle ride, cut a sandwich into three equal parts, and measure tall buildings while wearing silly shoes. But soon these hare-brained experiments begin to reveal a genuinely important truth- triangles are the hidden pattern beneath the surface of the contemporary world, used in everything from GPS to CGI via Spotify streaming, the play button and your best mate's triangle tattoo.
Join Matt Parker as he demonstrates why there's more to triangles than Pythagoras and SOHCAHTOA. Triangles are everything and everything is triangles.

Much sturdier than it seems!
I have a Lab/Pyrenees mix which is a serial toy defluffer. I truly believed these would be in the garbage by the end of a day or 2. Yes the squeakers are in the land of unnamed squeaker graves, but the actual pockets and Velcro lasting like a champ! It takes him a few minutes to unroll them and get the treats out of the pockets. When he gets the late night energy boosts I fill them up and it gets him calm for bed. He will bring them to me if he wants to search for the treats. One of our favorite things. Plus, they are adorable. Total tail wagger!

Puppy loves it!
Style: Turtle
This turtle is adorable!
My puppy absolutely loves it! It keeps her entertained for a while which is a godsend when potty training, and when I’m working from home. The pockets an are big enough to can stuff them full of tons of kibble or treats. She has so much fun playing with & pulling it apart and getting to the good stuff inside and the crinkly noise is a bonus for her as well. It definitely holding up.

Good value, fun play. Poor strings
Style: Monster
This turned out to be one of my Doberman puppy's favorite toys. He loves it and takes it everywhere. I didn't expect much, but the moment it came out of the box he loved it. The colors are still bright after a month of being knawed and chewed on. He loves playing tug a war with it, though the strings are not standing up to well to that. There are three of them, so he has choices. Pluse, he has an extra when missing one.
I think they are wonderfully well made and shaped well to fit for him to chew on. He hasn't torn any stuffing out of it and tears either despite his daily rough play. It is fun watching for seeing him attack those poor little guys.
The strings are only issue. It it slowly coming off in pieces. They are still hanging on, but dying a slow death. Pieces are being found all over the place. I keep a eye to try to make sure he isn't swallowing any.
I, also love the cute designs. The three different ones are so cute I don't have a favorite and neither does my puppy.
He will play with it for a while, not just tug a war. He likes the low low sounding squeaker. Low and now loud and annoying. The materials have a nice smooth feeling and no rough material. I don't mind holding on to it for tug a war or to throw it. It is easy to throw for him. Light but enough weight to send it though the air.
Great value fore the price and the amount of three. I would just take the strings off. They could possibly be a danger hazard.
Overall, I am glad I bought and a good value.
