Question

does the pythagorean theorem work only on right angle triangles?

Answer 1

Yes.

Answer 2

\[a^2 + b^2 = c^2\]

Only works if the lines for a and b are orthogonal to each other.

Answer 3

the pythag is a special form of

c^2 = a^2 +b^2 - 2ab cos(C)

where C = 90 degrees

Answer 4

cos theorem :)(I reviewed it today :P)
