**Summary**: *Symmetry came from the Latin symmetria, broken into syn (together) and metron (measure). Rotational symmetry (radial symmetry) is the feature of a shape when it stays the same after it gets rotated intermittently. One of the benefits or real-life applications of rotational symmetry is the utilization of windmills in the farm to generate the wind into electricity.*

### What is Rotational Symmetry?

We often hear the word symmetry in our daily conversation, but what is symmetry? Symmetry came from the Latin *symmetria,* broken into *syn* (together) and *metron* (measure). It is a situation when an object has an exact shape when it is divided in half. There are three kinds of popular symmetry: reflection, translational, and rotational. In this article, we will talk about rotational symmetry.

In geometry, rotational symmetry (radial symmetry) is the feature of a shape when it stays the same after it gets rotated intermittently. Some particular objects might be rational symmetry objects; however, only a few forms have perfect rotational symmetry, such as various spheroids (sphere and circle). One of the easiest ways to determine the rotational symmetry ability of an object is by drawing a straight line in the middle of the shape. Geometers refer to this line as the line of symmetry. The rotational symmetry theory clarifies the constancy of the object while it rotates on the axis.

### What are the Characteristics of Object with Rotational Symmetry?

Teaching the basics of geometry might be challenging for parents and teachers. However, once you catch their attention, this lesson could be a fun and exciting game for them. Before diving into the study, the adults (parents and teachers) should understand the concept of the topic first. This step is essential because children could ask various things related to the topic, so it will prepare the adults to answer them. Below are four characteristics of radial symmetry:

- The middle part of the object is the same as the heart part of the rotation.
- The rotation slant depends on the form of the shape.
- No matter on which angle the structure is fully rotated, the edge is 360°.
- The arrangement should be the same as the number of the complete turn.

### What is the Angle and Order of Rotational Symmetry?

There are many characteristics of rotational symmetry that children should master. Angle and order of rotation symmetry are two of them. The edge of rotation is a term in geometry to calculate the edge of the rotated object (usually the middle part of a circle). The swivel that follows the clock movement is a negative rotation. For example, if we turn an object 45 degrees, and the shape stays the same, the angular orbit of the object is 90 degrees. Meanwhile, the order is the amount of the stance the figure possessed and still looks the same before the rotation.

### What are the Uses of Radial Symmetry in Real Life?

In the paper, the topic of rotational symmetry looks complicated and tough to imagine. What are the use and the real-life application of this knowledge? These thoughts might block the lesson got absorbed into the brain. The Mathematician refers to the figures with radial symmetry as figures with no *up* and *down*, which gives many advantages in many kinds of machinery systems. One of the benefits or real-life applications of rotational symmetry is the utilization of windmills in the farm to generate the wind into electricity. Many industries followed the rule of rotational symmetry in producing their products. For example, there are snacks with triangle or circle shapes. Many machinery systems, such as the Ferris wheel, fidget spinner, dartboard and more, follow the law of radial symmetry. Understanding examples of rotational symmetry in real life will help the students to understand the lesson easier.

### How to Teach Geometry?

According to the research paper from Charles University, the Van Hiele learning model is the best suited to teach geometry to students. Van Hiele believed the success of geometry learning depends on the teacher's instruction while they lecture. This model offered a learning process consisting of five stages.

- The teacher explains the concept of geometry by having an engaged conversation with the students.
- The teacher assigns a simple task that helps them understand the knowledge better.
- The students explain what they have learned and discuss it with each other.
- The teacher gives the students a more complicated task to solve.
- The students conclude what they have learned.

### What are the Benefits of Learning Geometry?

Without we realized, there are many applications of geometry around us. The school system also includes this topic in the curriculum from kindergarten to twelfth grade. The university also offers classrooms for people who want to expand their knowledge in geometry. There are many benefits to learning geometry because it teaches us about the spatial of place, so it will help us get to know our surroundings. Learning geometry will also open many chances towards various jobs, such as architecture, engineering, astronomy, and more.
