Correct Question :-

Determine WHETHER the triangle whose length of side 3cm,4cm,5cm, is a right angled triangle .

= ${<klux>3</klux>}^{2}$ = 3 × 3 = 9; ${4}^{2}$ =4×4 = 16;

${5}^{2}$ = 5×5 = 25.

${3}^{2}$ + ${4}^{2}$ = ${5}^{2}$ .

$\huge \underline \bold{Therefore,}$

The triangle is right angled.
