1. Describes the relationship between the lengths of the hypotenuse and the lengths of the legs in a right triangle

2. In a Right Triangle The right angle is created by the legs a and b These are the shorter 2 sides of any right triangle The Hypotenuse c is across from the right angle It is the longest side c b a

3. 1.Square the lengths of the legs 2.Add the results together 3.Find the square root of the answer 4.Check to make sure it is longer than the legs Finding a hypotenuse

4. The length of a leg of a right triangle is 15 ft, the hypotenuse is 17 ft, find the missing leg. 15 2 + b 2 = 17 2 225 + b 2 = 289 289 – 225 = b 2 64 = b 2 Square root of 64 is 8, so b = 8 ft 1.Square the length of the hypotenuse and the leg 2.Subtract the results 3.Find the square root of the answer 4.Check to make sure it is shorter than the hypotenuse Finding the length of a leg

5. 1.Square the 2 numbers you know 2.Add or Subtract 3.Find the square root 4.Check to make sure it fits Remember:
