Angles larger than a right angle and smaller than a straight angle (between 90° and 180°) are called obtuse angles ("obtuse" meaning "blunt"). An angle equal to 1. /. 2 turn (180° or π radians) is called a straight angle.

Supplementary angle = 180 - 84 = 96 degrees.
It is a reflex angle because it is greater than 180 degrees
An angle of 220 degrees is a reflex angle
obtuse angle
Any angle between 90 and 180 degrees is an obtuse angle. Therefore: 160 degrees is an obtuse angle.
