Write down the measure of
(a) Some acute angles (b) Some obtuse angles (give at least two examples of each)
Let's look into the definitions of acute and obtuse angles.
Answer: (a) Some acute angles are 45°, 60° (b) Some obtuse angles are120°, 160°
Let's look into some examples
An acute angle is an angle whose measure ranges from 0° to 90° and is lesser than 90°
An obtuse angle is an angle whose measure is greater than 90° and lesser than 180°
