 NCERT Maths Concept

When two rays meet, they form an angle, and the angle formed by two rays facing opposite directions is known as a ‘Straight angle’.

An angle makes a straight line through the vertex.

A straight angle is one whose vertex has a value of 180 degrees in geometry.

Here, OX and OY are the arms of an angle. The vertex is the common point O where the rays meet.

How to represent a straight angle?

According to the measurement system, there are several ways to represent straight angles. 1. It is written as 180°  2. It is also written as π
