Question

An angled which measures more than 0${}^o$ and less than 90${}^o$ is called

• A. obtuse
• B. acute
• C. right
• D. none of these

Answer 1

The correct option is B acute

An acute angle is any angle smaller than ${90}^o$. A right angle is an angle that measures ${90}^o$. Angle greater then ${90}^o$ is obtuse angle.

$\Rightarrow$ An angled which measures more than $0^o$ and less than ${90}^o$ is called $acute.$

$\Rightarrow$ It doesn't matter how much smaller the angle is than

${90}^o$; as long as it's smaller, it's acute.

$\Rightarrow$ In diagram measure of $\angle ABC$ is ${60}^o$, which is less than ${90}^o$.

$\therefore$ $\angle ABC$ is acute angle.
