3. c a b Pythagorean Theorem
In a right triangle the sum of the squares of the measures of the legs equals the square of the measure of the hypotenuse. c2 a2 + b2 a2 + b2 >c2 a2 + b2 <c2 c
Hypotenuse a
Leg b
Leg

6. Converse of the Pythagorean theorem
If the sum of the square of the measures of two sides of a triangle equals the square of the measure of the longest side, then the triangle is a right triangle. If c2 = a2 + b2 ∆ABC is a right triangle. If c2 > a2 + b2 ∆ABC is a obtuse triangle. If c2 < a2 + b2 ∆ABC is a acute triangle B c a A b C

9. Is it a triangle? If so determine if the triangle is Right, Acute, or Obtuse
Right: c2 = a2 + b2 Acute: c2 < a2 + b2 Obtuse: c2 > a2 + b2
Let’s Practice:
1) a=14, b=5, c= ) a= 2, b=5, c=2
a=12, b=16, c=20 4) a=11, b=12, c=14
5) S(3, 3), T(5, 5) U(6, 0) 6) S(2, -1), T(5, 4), U(6, -3)
