Make a few acute angles and a few obtuse angles. Draw them in different orientations.
Draw acute angles (less than 90°) in various positions - some opening upward, some downward, some sideways. Draw obtuse angles (greater than 90° but less than 180°) similarly in different orientations. The orientation does not affect the angle type; only the measure matters. Acute angles appear 'sharp' while obtuse angles appear 'blunt'.
Explanation
The chapter explains that acute angles are 'less than a right angle or in other words, less than a quarter turn' while obtuse angles are 'greater than a right angle but less than a straight angle.' The question also mentions that 'Acute means sharp and obtuse means blunt.' Students should draw angles of various sizes in different positions to understand that orientation doesn't change the angle type.
