Detailed explanation-1: -When a soldier takes an “about turn ” he turns by 180∘, since he turns by a measure equal to two right angles.
Detailed explanation-2: -Angles that are 180 degrees ( = 180°) are known as straight angles.
Detailed explanation-3: -If we talk about a real-life example of a 180-degree angle, then a perfect example is the angle between the two hands of a clock at 6 o’clock. The angle between the two hands of the clock is 180° because it forms a straight line.
Detailed explanation-4: -An angle which measures more than 180∘ but less than 360∘ is called an obtuse angle.
Detailed explanation-5: -An angle whose measure is equal to 90° is called a right angle. A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle.
