Question

An angle which measures $0^o$ is called:

• A. obtuse angle
• B. straight angle
• C. zero angle
• D. right angle

Answer 1

The correct option is C zero angle

An angle which measure $0^0$ is called zero angle.

An angle which measure more than $0^o$ and less than ${90}^o$ is an acute angle.

An angle which measures ${90}^o$ is called a right angle.

An angle which measure more than ${90}^o$ and less than ${180}^o$ is an obtuse angle.

Hence, the answer is zero angle.
