Question

Triangle ABC has side lengths 9, 40, and 41. Do the side lengths form a Pythagorean triple? Explain.

Answer 1

Yes it forms Pythagorean theorem as the square of 9 and square of 40 when added together they form square of 49.
√9^2+√40^2=
√81+√1600=√1681=49

Answer 2

Hey friend
Pythagoras theorem=
H^2=P^2+B^2
H=41=the longest side
P=40=perpendicular
B=9=Base

41^2=40^2+9^2
1681=1600+81

Hence proved

Hope it helps you

Thanks
