Question

An angle which measures ${90}^o$ is called:

• A. obtuse angle
• B. acute angle
• C. right angle
• D. None of the above

Answer 1

The correct option is C right angle

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

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

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

Hence, the answer is right angle.
