In today’s post, we are going come learn around what an obtuse edge is with different examples take away from everyday life and also some smashville247.net exercises.

You are watching: What does a 120 degree angle look like

## What is an Obtuse Angle?

An angle is a space shared by two rays that space joined in ~ the exact same vertex. Us can discover different species of angle according to your amplitude.

If the amplitude is bigger than 90º (90 degrees) and less than 180º (180 degrees) that tells us that that is an obtuse angle.

An obtuse angle is likewise defined as an angle the is created when a beam rotates between 90º and also 180º about a point.

This obtuse angle procedures 130º.If you desire to refresh her memory around how to measure up an angle v a protractor, take a look in ~ this video clip tutorial about measuring angles:

## Properties of one Obtuse Angle

These angle measure in between 90º and 180º.Visually, this angle is an ext than a 4 minutes 1 of a circle yet less than half of a circle. So, if we division a circle into 4 parts, one obtuse angle will constantly occupy between 1/4 and also 1/2 the a circle.There is constantly an obtuse edge within one obtuse triangle.

## Examples of Obtuse Angles

The adhering to examples display that this angles constantly measure in between 90º and also 180º.

120º angle

This is one obtuse angle since 120 is a number higher than 90 and less 보다 180. For this reason this edge measurement is in between 90º and also 180º: 90º 135º angle

This angle is obtuse due to the fact that 135 is better than 90 and less than 180, as such it is between 90º and 180º: 90º 160º angle

This angle is obtuse too because 160 is better than 90 and also less 보다 180. The is in between 90º and 180º: 90º instances of Obtuse angles in daily Life

Have you ever before noticed the obtuse angles that you can find approximately you? there are fairly a couple of examples.

Take a look at the hands on this clock. The angle created by the clock hand is obtuse since it measures in between 90º and 180º. On analog clocks, friend can find even much more examples the times once obtuse angles are created by the clock hands, because that example, 3:35. Have the right to you find much more examples? Tell us in the comments!

This ballerina is able to stretch her legs come an amplitude the is characteristics of an obtuse angle. If she is may be to preserve her balance, and the amplitude, she have the right to turn come the other side and the angle would still measure the same.

Someone has eaten an ext than a quarter of this pizza, but less 보다 half. The part of the pizza that is lacking is an obtuse angle.

This fan is fully open and forms an obtuse angle. Look closely, if that is close up door a tiny bit, it is a right angle, and also if the is closed a bit more but no completely, it is one acute angle.

The angle created by the excavator’s arm creates an obtuse angle so that it will have the ability to dig right into the floor farther away than if it to be a smaller sized angle.
