Question

Triangle ABC has side lengths of 4 units, 7 units, and 5 units. Use the Converse of the Pythagorean Theorem to prove that ABC is not a right triangle. Write numbers 1-4 to order the steps.
16 + 25 = 49

a2 + b2 = c2

41 ≠
≠
49

42 + 52 = 72

Therefore, triangle ABC is not a right triangle.

Answer 1

Answer:

3

 16 + 25 = 49

1

4

41 ≠ 49

2

 4^2 + 5^2 = 7^2
