━━━━━━━━━━━━

❁ Step 1: Draw ∠ABC = 90°.

❁ Step 2: Draw an arc which intersects AB at P and BC at Q from point.

❁ Step 3: Draw an arc from point P by setting radius more than half of PQ.

❁ Step 4: Repeat step 3 using Q as a centre and intersect previous arc at R.

❁ Step 5: Join RB.

Therefore ∠RBC = 45°

Answer 2

${\huge{\rm{\underline{\underline{\rm{Question :-}}}}}}$

→ Using protractor, draw a right angle. Bisect it to get an angle of measure 45°.

${\huge{\rm{\underline{\underline{\rm{Answer:-}}}}}}$

→ Draw an ∠ABC of 90°

→ With center B and any radius , draw an arc which intersects AB at P and BC at Q.

→ With center P and Q and radius more than PQ draw two arcs which intersects each other at R

→ Join RB

∴ ∠RBC = 45°
