Example 3: quadratic graph (lines of symmetry) Write the equation of the line of symmetry for the quadratic equation y=x^2-8x+12 y = x2 − 8x + 12. Locate the centre of the 2D shape. Show step. Here, rather than locating the centre, we are going to locate the turning point of the curve.
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.

In mathematics, especially in geometry and its applications, an object is said to have symmetry if it can be divided into two identical halves. For example, look at the given picture of a flower: If we were to draw an imaginary line in the middle of it, we could divide it into two equal parts like this: Note that the two parts are identical and mir...
Let’s look at this flower again, the dotted line along which we divided it into two identical halves is called the line of symmetry or the axis of symmetry. It can also be defined as the line along which we can fold the object and its left and right half would completely overlap with each other. In mathematics, there are three types of lines of sym...
Symmetry was taught to humans by nature itself. A lot of flowers and most of the animals are symmetric in nature. Inspired by this, humans learned to build their architecture with symmetric aspects that made buildings balanced and proportionate in their foundation, like the pyramids of Egypt! We can observe symmetry around us in many forms: 1. Tree...
Example 1: How many lines of symmetry does the given figure have? Answer: Only one line of symmetry. Example 2: Can you find any examples of letters from the alphabet that have a horizontal line of symmetry? Answer: A lot of letters, like O, D, H, have horizontal lines of symmetry. Example 3: Is the given shape symmetric or asymmetric? Answer: The ...
For example a triangle can either have three (equilateral), one (isosceles), or no (scalene) lines of symmetry. These worksheets explains how to recognize and apply symmetry. These worksheets contain simple activities for students to teach them about lines of symmetry. Activities include determining if a shape is symmetrical, and identifying ...
Example 3: using angles. Show that the hexagon below has no lines of symmetry. Locate the centre of the 2D shape. Show step. Draw a small x x in the centre of the hexagon (this does not have to be exact): Use a ruler to visualise a horizontal and/or vertical line of symmetry through the centre of the shape. Show step.

Symmetry in a figure exists if there is a reflection, rotation, or translation that can be performed and the image is identical. Rotational symmetry exists when the figure can be rotated and the image is identical to the original. Regular polygons have a degree of rotational symmetry equal to 360 divided by the number of sides.
