Drawing Pythagoras' 3 4 5 Triangle

250 x 160 mm / 10 pages / full colour

The traditional geometrical construction of Pythagoras' famous 3 4 5 right angled triangle is shown with, additionally, a compass geometry that evolves from the 5 side of the triangle (the hypotenuse) if it is drawn as the diameter of a circle, a method that does not require the separate construction of right angles.

Two visual proofs of the theorem, that the square on the hypotenuse equals the sum of the squares on the other two sides, are also shown.
