pythagorean thmU6: C 1.1  & 1.3
 calculate the missing side of a right triangle 
by using the Pythagorean Theorem.
If a2 + b2 = c2 , then it's a right triangle
If a2 + b2 = c2 , then Not a right triangle
32 + 42 =5² 9 + 16 = 25 25 = 25
22 + 62 =7²

2.Pick one side as a, one as b.
3.Fill the values into the equation.
4.Solve for the unknown variable. b = 12 cm.
a =
m
Watch & Listen Calculate the length of the hypotenuse c when the sides are as follows.
a = 5 cm, b = 12 cm.
Calculate the length of the hypotenuse c when the sides are as follows.udo
Example1 a = −5 and b = −12
