Question

Write down the measures of
(a) some acute angles
(b) some obtuse angles
(give at least two examples of each).

Answer 1

a) Acute angle: The measure of the angles between $0^{\circ }$ and ${90}^{\circ }$ are called Acute angle. (OR) We can say simply smaller than right angle (${90}^{\circ }$).
So, the examples of it are ${45}^{\circ },{70}^{\circ }$

b) Obtuse angle: The measure of the angles between ${90}^{\circ }$ and ${180}^{\circ }$.
So, the examples of it are ${105}^{\circ },{132}^{\circ }$.
