Pythagorean Theorem
use Pythagorean theorem (A2 + B2 = C2).A is a side touching the right angle, B is the other side and C is the hypotenuse. example: A = 3, B = 4, C = ?, A2 + B2 = C2, 32 + 42 = c2, 9 + 16 = c2, 25 = c2 5 = c
C8
If you know the base and the hypotenuse (the other line that isn't the height), the hypotenuse squared minus the base squared equals the height squared. Example: base = 5 hypotenuse = 13 a2 - b2 = c2 25 - 169 = c2 144 = c2 12 = c height is 12
Use this A2 plus B2 = C2 32 + 52= C2 9+25= C2 34=C2 Square root of 34 = 5.83
