2.Which set of numbers could represent the lengths of the sides of a right triangle?

9, 40, 41

12, 15, 20

2, 3, 4

8, 9, 10

Answer 1

To find which set is formed a right triangle use Pythagorean theorem formula:
a^2+b^2=c^2

1.
7,24,25
7^2+24^2=25^2
49+576=625
625=625. Yay! This is the set that formed right triangle

2.
9,40,41
9^2+40^2=41^2
81+1600=1681
1681=1681. Yay! This set is formed right triangle. Hope it help!

Answer 2

Using Pythagoras theorem the set of numbers that represents the sides of a right angle triangle are 7, 24, 25 and 9, 40, 41

Using Pythagoras theorem to know the sides for right angle triangle.

The sides must obey Pythagoras rule to become a right angle triangle.

Therefore,

c² = a² + b²

where

• a and b are the legs
• c = hypotenuse side

Therefore,

7² + 24² = 25²

49 + 576 = 625 (This is a right angle triangle)

9² + 40² = 41²

81 + 1600 = 1681 (This is a right angle triangle)
