Question

How do I use the Pythagorean Theorem to find missing measures?

Answer 1

given any right triangle it will have 3 sides, two being the legs,one being the diagonal or hypotenuse
call them a,b,c
c=diagonal
a^2 +b^2 = c^2
given 2 of the lengths you can solve for the missing one.
ex: a=2, c=4
2^2 + b^2 = 4^2
4+b^2 = 16
b^2 = 16-4=12
b=sqrt(12) = 2*sqrt(3)
