Answer 1

Acute Angle: 1 Mark
Right Angle: 1 Mark

Angles are classified based on their measure as:

(i) Acute Angle: An angle that is > 0 and < 90${}^{\circ }$ is called an acute angle.

(ii) Right Angle: An angle that is exactly equal to ${90}^{\circ }$, is called a right angle.

(iii) Obtuse Angle: An angle that is > ${90}^{\circ }$ and < ${180}^{\circ }$, is called an obtuse angle.
