Write down the measure of (a) Some acute angles (b) Some obtuse angles (give at least two examples of each)

Solution:

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^°

Thus, (a) Some acute angles are 45^°, 60^° and (b) Some obtuse angles are 120^°, 160^°.

Write down the measure of (a) Some acute angles (b) Some obtuse angles (give at least two examples of each)

Summary:

(a) Some acute angles are 45^°, 60^° (b) Some obtuse angles are120^°, 160^°
