Rohan thinks he knows how to bisect angles and follows following steps to construct \[45{}^\circ \]angle. Step 1: Construct an angle of\[~90{}^\circ \]. Step 2: Bisect the \[~90{}^\circ \] angle. Step 3: Bisect one of the angles obtained in step 2. Which steps is not required to construct a \[45{}^\circ \] angle?
