    sin^2 + cos^2 = 1

    http://en.wikipedia.org/wiki/Pythagorean_theorem It's really not that hard.. Just a^2 + b^2 = c^2

    okay so if they gave me the numbers a=5, b=3, and c=7, and thn they ask me if the triangle was a right triangle, how would i figure that out?

    You would then need the sin/cos stuff... you taking trig yet?

    You don't need trig the c^2 bit is always the hypotenuse which is the longest side. so in that example. 3^2 = 9 5^2=25 9 +25 = 34 7^2 = 49 so a^2 + b^2 isn't equal to c^2 so it isnt right angled

    so if the problem was 1^2+9^2=c^2 then the answer would be radical 82?
