Answer
(i) 56° lies between 0° and 90°.
∴ 56° is an acute angle.
(ii) 125° lies between 90° and 180°.
∴ 125° is an obtuse angle.
(iii) 90° is exactly a right angle.
∴ 90° is a right angle.
(iv) 180° is exactly a straight angle.
∴ 180° is a straight angle.
(v) 215° lies between 180° and 360°.
∴ 215° is a reflex angle.
(vi) 328° lies between 180° and 360°.
∴ 328° is a reflex angle.
