Question

the sides of a triangle measure 15cm,36cm and 39cm .Show that it is a right angled triangle

Answer 1

If the triangle is right-angled, then it will obey Pythagoras Theorem.
$15^{2}$ + $36^{2}$ = 225 + 1296
                                                           = 1521
$39^{2}$  =  1521

Therefore, $15^{2}$ + $36^{2}$ = $39^{2}$
It obeys Pythagoras Theorem.
Hence, it is a right-angled Triangle.
