Types Of Angles

What are the different types of angles? To mathematics, angles are a very important concept, especially when it comes to geometry. They are composed of a vertex and two endpoints. There are many different types of angles. They depend on the place and the direction of the endpoints that are connected to the vertex.

The most common of the types of angles is the right angle. This is the types of angles wherein one of the endpoints is pointing directly upwards from the vertex and the other one is horizontal from it. This angle has a measurement of 90 degrees. When compared to a clock, the right angle forms at 3 o’clock, at 6:15, at 6:45, and many others.

An acute angle is among the types of angles that have a measurement of below 90 degrees. If you look at a clock, you can see an acute angle when the time is 3:10, 2:55, 10:40, and many others.

Obtuse angles, on the other hand, are types of angles that have measurements of more than 90 degrees but less than 180 degrees. When you look at the clock, you can see an obtuse angle when it is 3:55, 6:10, 8:30, and many others.

Straight angles are, well, angles that form a straight line. They measure exactly 180 degrees. When you look at a clock, you can see a straight angle when it is 6:00, 3:45, 10:15, 4:50, and many others.
Reflex angles are types of angles that form a measurement of more than 180 degrees but are not as big as 360 degrees. In clocks, reflex angles can be seen when it is 3:35, 1:25, 6:50, and many others.

Next, we have adjacent angles. These are angles that are composed of two angles that have a common vertex. This common vertex is called the adjacent angle. Unlike the many other types of angles, the adjacent angle cannot easily be seen on the clock. You can see it, however, when a clock has an arm for seconds. In this case, an example of an adjacent angle would be 3:50 where the arm for seconds can be found somewhere in the 10 seconds mark. The common arm would be the seconds arm and the vertex will be the point where the three arms meet.

Complementary angles are types of angles that are composed of two angles that have the measurement sum of 90 degrees. They can be adjacent angles sometimes and sometimes they are not. Much like adjacent angles you can only see complementary angles when there is an arm for seconds on the clock. In these cases, a good example would be 6:15 where the seconds arm is somewhere around the 20 to 25 seconds marks.

Lastly, we have the supplementary angles. These are types of angles, two angles that have the sum measurement of 180 degrees. They can also be adjacent angles. Supplementary angles can be made up of a straight angle and an acute angle. For instance, when you look at a clock, you can see this at 3:45 with the seconds arm somewhere between the 45 second and the 15 second mark.
