how to draw a 150 degree angle with a ruler and a compass
Here is the answer to your question.
Follow the steps to draw an angle of 150°
Step 1: Draw a line AB.
Step 2: With O as centre and a suitable radius, draw an arc intersecting AB in C and D.
∴ ∠AOB = 180°
Step 3: With D as centre and same radius, draw an arc intersecting the previous arc in E. Join OE.
∴ ∠BOE = 60°.
Step 4: Draw OF as the bisector of ∠BOE.
∴ ∠BOF = 30°.
Now, ∠AOF = ∠AOB – ∠BOF = 180° – 30° = 150°.
