প্রথমে পূরক কোণ কাকে বলে তা জানার জন্য এখানে ক্লিক করুন।

একটি কোণ $x$ ডিগ্রি হলে কোণটির পূরক কোণ হবে $\left(90^\circ-x\right)$ ডিগ্রি।

শর্তমতে,

$x=\frac{\left(90^\circ-x\right)}2$

Or, $2x=90^\circ-x$

Or, $2x+x=90^\circ$

Or, $3x=90^\circ$

Or, $x=\frac{90^\circ}3=30^\circ$

Answer : $30^\circ$
