Vicious Circles and Other Savage Shapes

Suitable for ages 10 upwards
This is probably the only maths book you'll ever read that has ABSOLUTELY NO SUMS!
All the answers are here, as well as a duel between Urgum and Grizelda, diabolical challenges from Professor Fiendish, academic punch ups between the Pure Mathematicians and a panic when Dolly Snowlips "cooks" Porky Boccelli a birthday treat.

An invitation to see our treasured ancient Greek sand doodles which demonstrate the basics of shape or "geometry" as it used to be called.
After we've learnt how to confuse teachers with a bit of Latin, we pick up some skills with compasses and rulers - and then help Veronica avoid an unwanted snog and get a naked colonel safely from the sea into his beach hut.
EXTRA: How to turn a rectangle into a square of the same area.
A packed chapter showing how a triangle could help Pongo McWhiffy stop Veronica fall into a cowpat and why milking stools have three legs. A particularily smelly Professor Fiendish has a particularily diabolical challenge, the gangsters find out how to divide up all sorts of strange shaped cakes without fighting - but the punches fly anyway as the Pure Mathematicians discuss where the centre of a triangle really is.
EXTRA - The Bear Hunter Puzzle with more answers than you'll find in the book! There's also a small printing error - did you spot it?
Not only do we learn how to draw different polygons, we also learn how to fold them and then throw a party to celebrate! We discover why bees are better builders than us and how to impress an alien waitress, and we prove to a judge the rules about polygon angles. We also find out what makes a Gollark laugh and see how to make the two "Penrose Tiles" which produce patterns that evolve into infinity!
EXTRA - The Amazing Penrose Chickens
EXTRA - How to calculate the formula for any regular polygon
It's amazing what you find when you play around with a couple of circles and a few straight lines! A visit to the Foul City of Fastbuck ends in crawling over a tank of twitching tongues and once again we dazzle the judge with some nifty proofs. Finally we go right back in time to see why Udd the caveman's super turbo charged six geared car doesn't impress the ladies!
EXTRA - The Names of Bits of a Circle
EXTRA - The Alternate Segment Theorem
EXTRA - How to find the Centre of a Circle using this book
Meet the five regular solids - and find out how the ancient Greek Plato tried to explain
how the world was made out of them.
See how Riverboat Lil manages to beat Brett Shuffler at snakes and ladders with a very
sneaky die and find your way around the octahedral planet Ptuon.
There's also instructions for building a "superstar" - but since the book came out, an MM reader called STEVEN CHARLTON told us its proper name is a "small stellated dodecahedron". Thanks Steven!
EXTRA - The Regular Solids - and how to work out their volumes!
EXTRA - How to make The Magical Self-Assembling Cube!
EXTRA - The 11 different cube nets.
A Pure Mathematician gets rather squashed as he asks "is an ellipse
just a squashed circle?" We meet ellipses of all sorts ranging from the all round sensible
ones to the raving eccentric bing-bong-whoopee type. Whether it's in a cathedral dome,
or a planetary orbit, we see why ellipses are not egg-shaped and how ellipses
save the planet from yet another evil Gollark plan.
EXTRA - How to work out the Area of an Ellipse and the volumes of ELLIPSOIDS!
He had it coming. 25 centuries ago Pythagoras lumbered us with his "theorem" about the square on the hypotenuse - so we bring him to life, shove him in front of the judge and make him explain himself. (This is all illustrated with about 6 pages of superb cartoon strips by Philip Reeve.) But then the big problem is that now he's alive, what do we do with him?
EXTRA - How to make a Hexaflexagon
