➤Diagram ❁

• In the attachment.

➤Steps of Construction ❁

• ⚫ Draw AB ray with initial point A.

• ⚫ Taking A as a centre and with any radius, we draw an arc which cuts AB at D .

• ⚫ Taking D as a centre and with the same radius, we draw another arc which cuts the previously drawn arc at E .

• ⚫ We draw AC passing through E.

• ⚫ Taking E and D as a centre and taking the radius more than half of ED , we draw two arcs which arc at F .

• ⚫ We join AF.

∴ ∠FAB is the required angle of 30°

➤Material Used ❁

• ➡️ Ruler:- A ruler is also known as scale.

• ➡️ Compass:- A compass is used for drawing circles or parts of circles called arc.
