Can you form a right triangle with the three lengths given: 7 in., 24 in., 25 in.?
This only works if the square of the largest number is the sum of the two other squares.
We have to check if:
Conclusion : Yes, we can!
The Pythagoras theorem states that:
"In a right-angled triangle the squares of the sides add up to the square of the hypotenuse"
But it also states the reverse:
"If the squares of the sides add up to the square of the hypotenuse, then we have a right-angled triangle".
