How many degrees in a Straight Angle?

A straight angle is an angle equal to 180°. It looks like a straight line. We know that an angle is formed when two rays meet. When two rays meet to form a Straight Angle which is equal to 180° then it can be seen that they are in one direction forming a Straight Line and hence called Straight Angle.

Properties of a Straight Angle

The different properties of Straight Angle are listed below:

A straight angle always measures 180°.
Straight angles create a straight line.
It is denoted by π (i.e. π = 180°)
It is also called the angle of a straight line.
The two rays form a straight angle point in precisely opposite directions.
It can be formed by joining two right angles (i.e. 90° + 90° = 180°)

Straight Angle

Straight Angle, is essentially a perfectly straight line and measures 180°. Straight is the simplest and most basic angle in geometry.
Imagine a line that doesn’t bend or curve at all, just like a super straight road. Well, that’s what we call a straight angle. It’s just like a flat line that goes straight ahead. This angle is not only easy to visualize but also serves as a reference point for various geometric principles. Let’s understand more about Straight Angles by briefly learning about angles and their types.
