Answer 1

Follow Steps⠀⠀⠀⠀:

1️⃣ Draw a ray OA ( Image 1 )

2️⃣ Place center of protractor ( D ) on point O, and coincide line OA and protractor line.

3️⃣ Mark point B on 90°

4️⃣ Join OB

$\angle AOB ⇒ 90°$

Now we need to find it's bisector

$\huge{ \overline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}$

1️⃣ Mark points C and D where are intersects OA and OB

2️⃣ Now taking C and D as Centers

$\sf and \: with \: the \: radius \: more \: than \: \frac{1}{2} CD,$

Draw ARCS to intersect each other.

3️⃣ Let them intersect at point E.

4️⃣ Join O & E

$\sf • \: O \: and \: E \: is \: the \: bisector \: of \: \angle BOA \implies90 \degree$
