Question

the triangles with sides 13 cm ,16 cm and 18 cm forms a right angle triangles. state ture or false

Answer 1

Answer:

if it is a right triangle, we should get,

18^2=16^2+13^2

324 is LHS part

256+169 is RHS part

256+169=425

which is not equal to LHS.

So it is false.

Answer 2

if it is a right angle triangle we get

${18}^{2} = {13}^{2} + {16}^{2}$

$324 = 169 + 256$

$324 \: not \: = to \: 425$

so it is not a right angled triangle
