Question
For making an angle of 105∘, you need to construct a 60∘ angle too.
Answer: Option A
:
A
A105∘ angle can be constructed by drawing a bisector between 120∘ angle arm and 90∘ arm as shown in the figure below. But it can be seen clearly that for making 120∘ and 90∘ angles, one needs to make a 60∘ angle first. In the image given, ∠DAB will be 60∘ .
