It seems that almost everyone agrees that mathematics is the most challenging lesson in school. In addition to meeting numbers and counting, many formulas and figures need to be remembered so that they can facilitate us in calculating.

One sub-chapter that has much material to understand and memorize is a pie chart. By studying circle charts, the trigonometric concept will also be more easily understood. However, remembering, of course, requires tools to facilitate mastery of the material.

The **circle chart unit** is one of the tools in mastering trigonometry and diagram material. When studying mathematics, some people need a flashy image to master matter compared to the imagination. The unit circle chart will make a circular diagram real to help with the teaching and learning process.

In this unit, there is a circle, along with possible angles. Circles in a circle chart unit also provide greater distance to measure each corner. Therefore, the circle is more popular with many people in mastering the material compared to the right triangle.

**Tips on making a circle chart on your unit**

Maybe there are some people who, instead of downloading, want to create their circle charts to understand the concept of pie charts better. For that, of course, you need a few tips to do it. Here are some tips:

- The first step is to make the first quadrant of the pie chart. That is a 30O angle for the unit circle.
- Then draw each corner carefully; after that, the origin is connected to the edge with a straight line.
- Previously it would be best if you made sure that the 30O that you have drawn is in the first quadrant
- The next step is to create a perpendicular line. This line will help them to make a right triangle.
- From the vertical lines that are made, the hypotenuse of the triangle will be formed, which is also the radius of the unit circle with the x and y-axes on each leg.
- Then your next task is to look for the sloping side. Noteworthy is that in units of circles, the radius is always 1. Therefore the length of the hypotenuse is also automatic 1.
- In addition to the fingers and the sloping side, you also need to find out the other hand. The trick is to calculate the shorter side by dividing the value by 2. As for the long side, the value of the small team at times two, then the result is the high side value.
- Next, you need to indicate the point on the circle you made. The coordinates that have an origin at the center are unit circles. If all the tips have been run, it will be an easy job for you to find another corner point.

Mathematics is a lesson related to numbers wherein each sub-chapter there are many formulas and material that must be understood. One of them is a circle chart. With a **circle chart unit**, learning circle charts will be more comfortable and more convenient.
