1. Answer in a short paragraph and with diagrams
a(squared) + b(squared) = C(squared)
This Pythagorean Relationship means that the legs of the right triangle together equals to the hypotenuse, which is the longest side length of the right triangle. Say if the side lengths of the right triangle (A and B) were 4 and 3 and the hypotenuse (C) was 5. You would sub the letters to numbers.. so it would be 4(squared) + 3(squared) = 5(squared). Squared means to times it's number by it self, so it would be 4x4+3x3=5x5. So now you multiply the numbers, 4x4=16, 3x3=9, 5x5=25. 16+9=25, Both of the legs together equals to the hypotenuse, therefore it is a right triangle.
2. Solve for the missing side length.
3. Is this a right triangle? Prove it!!!
