Question

Is the following angle acute, right, obtuse or straight ?

• A. Acute angle
• B. Right angle
• C. Obtuse angle
• D. Straight angle

Answer 1

The correct option is C Obtuse angle

When the angle formed between any two rays is more than 90 ${}^{\circ }$ and less than 180${}^{\circ }$, then it is called an obtuse angle.
Here in the figure, the angle is more than 90${}^{\circ }$ and less than 180${}^{\circ }$. So it is an obtuse angle.
