Understanding the Size and Classification of a 120º Angle

120º

The value 120º refers to an angle measurement in degrees

The value 120º refers to an angle measurement in degrees. An angle is formed by two rays that share a common endpoint, also known as the vertex. In this case, the angle being referred to is 120 degrees.

To better understand the size of a 120º angle, we can consider it in relation to a full circle. A circle is divided into 360 equal parts, each part representing 1 degree. So, a full circle would consist of 360º.

Since 120º is less than a full circle, it represents a smaller angle. We can think of it as one-third of a full circle, as 120º is exactly one-third of 360º. In geometric terms, one way to imagine a 120º angle is by picturing a clock face. If the hour hand were pointing at the 4 on the clock, while the minute hand was pointing directly at the 12, the angle formed between the hour hand and the minute hand would be 120º.

It’s important to note that angles can also be categorized based on their size. A 120º angle falls into the category of an obtuse angle, which means it is greater than 90º but less than 180º.
