What is the thoerem of Pythagoras?

Answer 1

thePythagoras theorem was simply to calculate the sides of a right angled triangle, isosceles triangle and cubes and cuboids

here is the formulas;

right angled triangle= a^2+b^2=c^2

for an isosceles triangle, split it in half and you have two right angled triangles, use the formula above afterwords

cube/cuboids, you can find the face diagonal and the space diagonal by using the formula above

to calculate if it is a right angled triangle or not, then you need the 3 sides( a, b and c)add a^2 and b^2, then calculate c^2, if a^2+b^2 is equal to c^2, then it is a right angled triangle, if not, then it isn't a right angled triangle by the converse of Pythagoras, hope this helped :-) hope its not to complicated for you!
