Do you know how to find if areas of two smaller pizzas are equal, smaller or greater than larger one. Smaller:If angle between two smaller pizzas are great than 90. Equal:If angle between smaller pizzas are 90 degree. Bigger:If angle between smaller pizzas are less than 90 degree. Pythagorean triple holds if there is 90 degree angle(between smaller pizzas) when vertices of pizzas touches. Pythagorean Theorem: when angle is 90 degree. Sum of squares of diameters of smaller pizzas are equal to square of diameter of larger pizza.
