In today’s post, we room going come learn about what an obtuse angle is with different examples taken from day-to-day life and some beer-selection.com exercises.

You are watching: What does a 130 degree angle look like


What is one Obtuse Angle?

An edge is a room shared by 2 rays that room joined in ~ the same vertex. Us can find different species of angle according to their amplitude.

If the amplitude is larger than 90º (90 degrees) and less than 180º (180 degrees) the tells united state that it is an obtuse angle.

An obtuse angle is also defined as an angle that is developed when a beam rotates in between 90º and 180º around a point.

This obtuse angle measures 130º.If you want to refresh your memory about how to measure up an angle with a protractor, take it a look in ~ this video tutorial about measuring angles:


Properties of one Obtuse Angle

These angles measure between 90º and also 180º.Visually, this edge is much more than a 4 minutes 1 of a circle but less than fifty percent of a circle. So, if we division a one into four parts, an obtuse angle will always occupy in between 1/4 and also 1/2 that a circle.There is constantly an obtuse edge within an obtuse triangle.

Examples that Obtuse Angles

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

120º angle

*

This is an obtuse angle since 120 is a number better than 90 and less 보다 180. So this edge measurement is between 90º and 180º: 90º 135º angle

*

This edge is obtuse because 135 is greater than 90 and also less than 180, because of this it is in between 90º and 180º: 90º 160º angle

*

This edge is obtuse as well because 160 is higher than 90 and also less 보다 180. That is between 90º and 180º: 90º examples of Obtuse angle in everyday Life

Have you ever noticed the obtuse angles that you deserve to find around you? over there are rather a few examples.

Take a look in ~ the hands on this clock. The angle created by the clock hands is obtuse because it measures in between 90º and also 180º. On analog clocks, girlfriend can uncover even much more examples that times when obtuse angle are formed by the clock hands, for example, 3:35. Have the right to you find more examples? Tell united state in the comments!

This ballerina is able come stretch her legs come an amplitude the is characteristics of an obtuse angle. If she is maybe to keep her balance, and also the amplitude, she deserve to turn to the other side and also the angle would certainly still measure up the same.

*

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

*

This fan is totally open and forms one obtuse angle. Look at closely, if it is closeup of the door a small bit, the is a ideal angle, and if the is closeup of the door a bit more but no completely, that is an acute angle.

*

The angle created by the excavator’s arm forms an obtuse angle so the it will be able to dig into the soil farther away 보다 if it to be a smaller angle.
