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.

We have a number of figures in mathematics that are so evenly balanced n different sizes and shapes. Let us observe the following figures – We can observe that for each figure the one half on one side of the dotted line is exactly identical to the one half on the other side of the dotted line. In other words, we can say that the two halves are mirr...
We say that a given line has a line of symmetry or it is symmetrical about a lineif the line divides a given figure into two identical halves. The line is called the axis of symmetry or line of symmetry.
There are two types of line symmetries according to which we can classify the symmetries in different geometrical figures. These types are – 1. Horizontal Lines of Symmetry 2. Vertical Line of Symmetry Let us discuss them in detail
A geometrical figure is said to have one line of symmetry if it is symmetrical about one line of axis only. Let us consider some examples.
A geometrical figure is said to have two lines of symmetry if it is symmetrical about two lines of axis only. Let us consider some examples.
A geometrical figure is said to have three lines of symmetry if it is symmetrical about three lines of axis only. Let us consider some examples.
A geometrical figure is said to have four lines of symmetry if it is symmetrical about four lines of axis only. Let us consider some examples.
A geometrical figure is said to have five lines of symmetry if it is symmetrical about five lines of axis only. Let us consider some examples.
A geometrical figure is said of having six lines of symmetry if it is symmetrical about six lines of axis only. Let us consider some examples.
A geometrical figure is said of having infinite lines of symmetry if it is symmetrical about infinite lines of the axis. Let us consider some examples.
Example 4: As shown in the diagram, this is one half of a symmetrical shape. Complete the shape by drawing the rest of it. Solution: Method 1: First, create a line of symmetry. On the other side of the line of symmetry, draw the other half of the shape. Method 2: First, create a line of symmetry.

Any object or shape which can be cut in two equal halves in such a way that both the parts are exactly the same is called symmetrical. The line which divides the shape is called the symmetry. So, if we place a mirror on the line of symmetry we can see the complete image. When a symmetrical shape is folded along the line of symmetry, one half of ...
