Seven Symmetry Activities. 1. Symmetry Art Swap. For this activity, you’ll want to provide individuals with graph paper and art supplies. Every student will begin by creating a “line of symmetry,” preferably horizontal or vertical to begin with, through the center of the page. Then, they can create a geometric design of their liking on ...
4 Draw a line from each vertex through the center and check for line symmetry. 5 State the number of lines of symmetry. The equilateral triangle has 3 3 lines of symmetry. An equilateral triangle has 3 3 equal sides and 3 3 equal angles, so it will have 3 3 lines of symmetry.

- Activities For Your Classroom.
On the national curriculum, symmetry makes its appearance in year two, and it is practised throughout a student’s education. The learning outcome for students is that: 1. Students should be able to identify lines of symmetry in 2-D shapes and identify the properties of each shape including the number of sides and faces. 2. Students should also draw...
What is it?
The line where the shape is cut exactly in half. This means that if you were to cut the shape in half (using your line of symmetry) both halves would be equal. If you were then to place them back together, the shape would still be the same.
Why do we use it?
The line of symmetry is a fundamental part of geometry, the world, and shapes. As mentioned above, a line of symmetry aids with measuring in equal parts, but it also helps us identify how to rotate, translate, and reflect other shapes. Symmetry is in nature, but many people often do not recognise it, examples of symmetry in the world would be butterflies, flowers, feathers, some insects, animals, buildings.
In maths, especially geometry, a 2-D shapes stands for a two-dimensional shape. These shapes are flat, and only have two dimensions: length and width. 2-D shapes do not have any thickness and usually only have two faces.
Understanding symmetry can sometimes be a challenge for those students who are not “visual learners”. To help, Emile has come up with seven activities that might be useful for your classroom.
- Geo boards. A geoboard is a panel with nails on it, ensuring the practitioner wove thread along them to form shapes like triangles, polygons, and so on.
- Origami. Origami is one of the oldest Japanese arts that is an excellent source of teaching symmetry. To start with, the mentor needs to procure a sheet of paper.
- Vegetable printing. This may be a facile way of noticing symmetry. To start with, Cut up a few vegetables like Okra, Onion and create prints on paper using paint or ink.
- Creating Mirror Books. To start with, Take two mirrors and tape them together at the right angle of the same size and width. Place it on a table, shelf, or on any flat surface.
Symmetry. In this section there are activities for exploring the concepts of symmetry. In each activity, you are urged to edit and play around with the shapes to create new shapes. Reflection Symmetry. Reflection Symmetry in Quadrilateral s (GGB) Reflection Symmetry in Triangles (GGB) Reflection Symmetry in Other Shapes (GGB) Rotational Symmetry.
Example 2: a rectangle (lines of symmetry) Locate the center of the 2D shape. Show step. Draw a small x x in the center of the square (this does not have to be exact). This is also known as the central point of the shape. Draw a horizontal and/or vertical line of symmetry through the center of the shape. Show step.
