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:
Question 10: Colour the appropriate cells to make it symmetrical for the given image. Solution: There are multiple ways to make the given image symmetrical. 3 methods are given below. Method 1: Colour all cells with the same colour. (either grey or white) to make it symmetrical. Method 2: Method 3:

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.
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.
Sep 24, 2024 · Symmetry and Line of Symmetry. Symmetry refers to a situation where one half of an object, shape, or image is a mirror image of the other half. We can also call symmetry a balanced and proportionate similarity between two halves of an object. Symmetry is often seen in nature, art, and design, where it creates a sense of balance and harmony.
Symmetry Examples. Example 1: If the following figure shows a reflexive line of symmetry, complete the figure. Solution: It is given that the figure has a reflexive line of symmetry. That means the second half or the missing part of the figure will be exactly the same as given on the other side.

How do you identify a line of symmetry?
A line of symmetry is the line that divides a shape or an object into two equal and symmetrical parts. We also call this line the axis of symmetry or mirror line because it divides the figure symmetrically, and the divided parts look like mirror reflections of each other. More line of symmetry examples are shown in the figure below.
