Answer
To measure a reflex angle, we first measure the smaller angle (less than 180°) using a protractor, and then subtract it from 360°.
(i) On measuring the smaller angle, we get 45°.
Reflex angle = 360° - 45° = 315°
(ii) On measuring the smaller angle, we get 125°.
Reflex angle = 360° - 125° = 235°
