Question

determine whether 50 cm 80 CM 100 cm can be the side of a right triangle or not

Answer 1

So, as we know that for a right angle,

$\bf \: (H )^{2} \: = \: {(P)}^{2} + {(B)}^{2}$

Where, H = Hypotenuse (Largest side of triangle)
P = Perpendicular
B = Base...

So, let's put the values and check if the given sides are sides of a Right Triangle or not.

${(100)}^{2} = {(80)}^{2} + {(50)}^{2} \\ \\ 10000 = 6400 + 2500 \\ \\ 10000 = 8900$

Since, they are not equal...

The given sides are not the sides of Triangles.

If any doubt, please ask ;)
