Each Point: 1 Mark

We know that a right angle is equal to 90${}^{\circ }$
a) Any angle less than a right angle is an acute angle.
b) If an angle is greater than 90${}^{\circ }$ and less than 180${}^{\circ }$, then it is called an obtuse angle.
If an angle is greater than 180${}^{\circ }$ then it is called a reflex angle.
