Question

Use the Pythagorean Theorem to confirm the three sides of a right triangle.

3. a = 5, b = 12,c = 13
4. a = 4, b = 10,0 = 20

Answer 1

3) confirmed right triangle

4) not a right triangle

Explanation:

3) 5^2 + 12^2 = 13^2

25 + 144 = 169

169 = 169

4) 4^2 + 10^2 = 20^2

16 + 100 = 400

116 does not equal 400
