Question

Could this below equation form a right triangle:
a). 8cm,11cm,19cm
b).7cm,√(76)cm,15cm

Answer 1

doesn't seem so. not if these are side lengths. for it to be a right triangle, the pythagorean theorem must hold true. it is:
\[a^2 + b^2 = c^2\]where c is the hypotenuse (the longest side)

plugging in values for these two triangles indicates this equation does not hold true, therefore they are not right.

THEY ARE WRONG.

Answer 2

both of them are wrong?

Answer 3

Yes both of them

Answer 4

Thanks so much :)
