Summary: Symmetry refers to a moment when we divide a shape; the cuts have the exact form. There are three types of popular symmetry: reflection, translational, and rotational. One of the easiest ways to define the symmetry ability of an object is by pulling a straight line in the middle of the shape. This line is known as the Line of Symmetry. There are three types of Symmetry Lines, horizontal, vertical, and diagonal.
What Does It Mean by Lines of Symmetry?
Are you familiar with the term symmetry? It is a common word in mathematics or geometry lessons. Symmetry came from the Latin symmetria, split into syn, which means together, and metron, which means measure. It refers to a moment when we divide a shape; the cuts have the exact form. There are three types of popular symmetry: reflection, translational, and rotational.
One of the easiest ways to define the symmetry ability of an object is by pulling a straight line in the middle of the shape. According to the lecturer from the Mathematics Department at the University of Illinois Urbana-Champahn, it is the line of symmetry. It is a streak that divides an object into two of the same form. We can also fold a piece of paper with a particular shape to check whether it has a line of symmetry or not.
How to Identify A Shape with Line Symmetry?
In mathematics or geography, we can say an object is symmetric if they have a line symmetry. It is a vital indicator to determine the symmetrical of a shape. We can define this aspect by drawing a straight line to a figure or folding it to create the streak in the middle of the form. Some experts also refer to this line as the axis of symmetry or mirror of the line. It is because the streak divides a shape symmetrically or turns an object into two identical ones as if they are in front of a mirror.
There are three types of symmetry lines:
- Horizontal Line: Horizontal Line refers to a straight line from left to right (or vice versa) on an object that divides a shape into two identical forms.
- Vertical Line: Vertical Line is a straight line that goes from top to bottom (or vice versa) of a shape, which makes them into two same ones.
- Diagonal Line: Diagonal Line is a sideways or slanted line that goes through a shape resulting in two identical forms.
How to Teach Line Symmetry to Young Students?
As in the previous part of the essential use of symmetry lines in real life, parents and teachers should teach the students about this lesson. The adults can trigger the children's geometry knowledge through this knowledge. The students need to learn about this lesson because it has various perks for their skill and knowledge growth. Some math education experts recommend that students use practical activities to help them study symmetry. Below are some examples of the suitable exercise to help students learn about this lesson:
- Make a loose part face.
- Create model.
- Use geoboards.
- Utilize the Seeing Symmetry Book to teach the students.
- Drawing a model beside a mirror.
- Paint printing with objects.
- Practice with worksheets.
Why Should Young Students Learn Line Symmetry?
Naturally, most humans thought something symmetrical was a perfect essence. Whether this perception is true or not, it depends on various aspects. This idea might come from the fact that we can spot many things with symmetry elements around them. It is also one of the common visions in design and architecture. Many thought that symmetry makes something looks more beautiful and neat. According to Oxford University, many nature elements are symmetrical, as well. Hence, we can conclude that learning about lines of symmetry could help humans understand Mother Nature. Learning about lines of symmetry also assists students in developing their skills in art or improving their creativity.
Many experts agree that learning about symmetry can help students prepare their foundation for learning advanced math. Various works require people to understand this knowledge. In mathematics, we know the importance of symmetry in the geometry chapter. It is a vital element that students should master. Many people also use the concept of symmetry, such as translations, rotations, reflections, and tessellations, in their education or career journeys. It also provides a sense of order and balance in design and art.
How to Improve Students' Geometry Knowledge?
Geometry is a natural element that we can find easily around us. Hence, learning about this topic will help us in various moments. Many experts stated that geometry is essential knowledge to learn. Parents and teachers should teach their kids and students to learn about geometry. There are various ways the students can improve their geometry knowledge:
- The teacher should ensure the students understand the concept of geometry.
- Use physical objects to study geometry.
- Join a study group or additional math class.
- Practice frequently with worksheets.
- Review and learn from the previous mistakes.
- Practice drawing various shapes.
