Question

Which of the following angles cannot be constructed using a protractor?

• A. ${45}^{\circ }$
• B. ${34.6}^{\circ }$
• C. ${60}^{\circ }$
• D. ${27}^{\circ }$

Answer 1

Answer: (B)

${34.6}^{\circ }$

Least count of protractor is $1^{\circ }$ that is minimum $1^{\circ }$ angle can be constructed using a protractor.

We can simply say angles constructed using protractor are of integral values.

So ${34.6}^{\circ }$ can not be constructed using protractor.
