Question

Select all side lengths that would form a right triangle.

Answer 1

Answer:

option 2 , 3 , 4 , 5

Step-by-step explanation:

Use Pythagorean theorem

hypotenuse² = base² + altitude².

If the lengths satisfies Pythagorean rule, then they form a right angle triangle.

2) 41² = 40² + 9²

1681 = 1600 + 81

1681 = 1681

41, 40 , 9 will form a right angle as it satisfies Pythagorean rule.

3) 15² = 12² + 9²

225 = 144 + 81

225 = 225

9, 12 , 15 will form a right angle as it satisfies Pythagorean rule.

4) 17² = 15²  + 8 ²

289 = 225 + 64

289 = 289

17, 15 , 8  will form a right angle as it satisfies Pythagorean rule.

5)53² = 28² + 45²

2809 = 784 + 2025

2809 = 2809

53 , 28 , 45 will form a right angle as it satisfies Pythagorean rule.
