Is a straight line 360 or 180?
Solution: The 180-degree angle is a straight line, known as a semi-circle. A 90-degree angle is one-fourth of a circle. 180 degrees form a straight line, while 90 degrees form a perpendicular line.

Is a straight line 90 degrees?
We've already said that a straight line contains 180 degrees. This means that if two or more angles lie in a straight line, the sum of their angles is 180 degrees.
What is 180 degree angle called?
straight angles Angles that are 180 degrees (θ = 180°) are known as straight angles.
Why a line is 180 degree?
It is called straight because it appears as a straight line. Basically, as per angles definition in maths, when two rays are joined end to end, they form an angle. Hence, the two rays of the 180-degree angle are subtended towards the opposite direction, where the rays are joined to each other at endpoints.
What is a 270 degree angle called?
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.
What is 90-degree angle called?

Which angle is 270 degree?
reflex angles 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.
What is called 360 degree angle?
Angles that are 180 degrees (θ = 180°) are known as straight angles. • Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles. • Angles that are 360 degrees (θ = 360°) are full turn.
