Angles are Spaces Created by Two Lines, Know Their Types

Kapanlagi.com - Mathematics is one of the basic subjects that is continuously taught at every level of education. In general, mathematics is known as the subject of calculations. In mathematics, there are various interesting topics to learn. One of them is the topic of angles. Not only interesting, knowledge about angles is also very important to master.

Knowledge about angles is very useful in everyday life. In general, the definition of an angle is a space created by two lines spreading from a single meeting point or vertex. As we know, the magnitude of an angle is expressed in degrees. Meanwhile, the maximum magnitude of an angle is 360 degrees.

In addition to the above description, there are still several things you need to know about angles. Therefore, read the following summary about angles that has been compiled from various sources.

1. Definition of Angle

To understand more deeply what an angle is, we need to examine the definition of an angle first. As mentioned earlier, an angle is a space or distance created by two lines spreading out from a common point or vertex.

Angles are expressed in degrees. The magnitude of an angle is within the range of 0 to 360 degrees. The notation for angle measurement is a number followed by the degree symbol, which is a small circle hanging above and behind the angle measurement number.

In everyday life, there are generally known to be several types of angles, namely acute angles, right angles, and obtuse angles. However, there are actually several other types of angles. Therefore, it is very important to recognize each type of angle, as each angle has different characteristics.

The following are some types of angles.

2. Types of Angles Based on Size

As mentioned earlier, an angle is a shape formed by two lines spreading from a vertex point. Various types of angles can be examined based on their sizes. Here are some types of angles based on their sizes.

1. Zero Degree Angle
A zero degree angle is an angle that has a size of 0 degrees. It means that a zero degree angle is formed by two lines that are adjacent, not intersecting, so in other words, it does not form an angle at all.

2. Acute Angle
An acute angle is an angle that has a size between 0 degrees and less than 90 degrees. Therefore, this angle produces a point that appears small or narrow.

3. Right Angle
A right angle has a size of 90 degrees, not less and not more. A right angle is formed by two lines that intersect at right angles.

4. Obtuse Angle
An obtuse angle is formed by the intersection of lines that form an angle between 90 degrees and 180 degrees.

5. Straight Angle
A straight angle has an angle size of 180 degrees, not less and not more. This straight angle is formed because when the angle size is 180 degrees, a straight line will be formed.

6. Reflex Angle
The second type of angle is often called a reflex angle. The size of a reflex angle is between 180 degrees and 360 degrees. Reflex angles are also formed when there are two intersecting lines and result in an angle between 180 degrees and 360 degrees.

7. Full Angle
As mentioned earlier, the largest angle measurement is 360 degrees. When an angle reaches this size, it is called a full angle.

3. Types of Angles Based on Their Position

In mathematics, angles are not only determined by their size. One indicator to determine the type of angle is by considering its position. Based on their position, angles are divided into several types, as follows.

1. Complementary Angles
The first type of angle based on its position is complementary angles. This type of angle represents two adjacent angles, with both of their sizes exactly 90 degrees.

2. Supplementary Angles
Similar to complementary angles, supplementary angles are also represented by two adjacent angles. However, supplementary angles have a total size of 180 degrees.

3. Adjacent Angles
The next type of angle is adjacent angles. This type of angle is formed by three lines intersecting at a single vertex.

4. Vertical Angles or Opposite Angles
Vertical angles or opposite angles refer to angles that are positioned opposite to each other and form an intersecting line.

Those are some explanations about the concept of angles, which are an important part of mathematics, along with their types. Hopefully, this information is useful and can enhance your knowledge.
