The pythagorean theoram talks about right triangles. The Formula: a^2+b^2=c^2 When there are missing legs in a right triangle you substitute what you know, and solve for what you don't know EX: 6^2+b^2=10^2 36+b^2=100 __-36__ __-36__ 0 64 Then you square root "b" and 36. And square root of 36 is 6. so b=6 [|Click here]

Formula:a^2+b^2=c^2 Legs: the sides of a right triangle Hypotenuse: the longest side of a right triangle exact: if you factor and get down to a square Approximate: answer in decimals EX 2: 3^2+4^2=5^2 9+16=25 25=25 Word Problems: Ex: 1: Town A is 9 miles from town B, and 12 miles from town C. A road connects town B and C directly. Find the length of this road 9^2+12^2=C^2 81+144=225 Then you square root 225 and C.       225 Squared equals 15(which is your answer)

EX 3: 9^2=x^2+7^2 81=x^2+49 32=x^2 then you square root 32 and x^2, and get 5.66 (which rounds up to 5.7)( [|CliCK hEre]style="COLOR: #1400ff">
