The lengths of 3 sides of a triangle are given. Use the Pythagorean Theorem (a? + b2 = c?) to determine if the triangle is a right triangle. (Show your work.)
1. a = 9 in, b = 12 in, c = 15 in
2. a = 8 cm, b = 15 cm, c = 17 cm
3. a = 3 m, b = 2 m, c = 13 m
Yes, it's a right triangle.
No, it's not a right triangle.
Yes, it's a right triangle.
No, it's not a right triangle.
Yes, it's a right triangle.
No, it's not a right triangle.
4. a = 2 ft, b= 1 ft, c=v5 ft
5. a = 5 m b = V11 m, c = 6 m
6. a = 2 m b = 6 m, c = 20 m
Yes, it's a right triangle.
No, it's not a right triangle.
Yes, it's a right triangle.
No, it's not a right triangle.
Yes, it's a right triangle.
No, it's not a right triangle.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
