Question

Copy the figures with the punched holes and find the axes of symmetry for the following-

Answer 1

The axis of symmetry is an imaginary line passing through a body or a figure which divides it into two equal parts or halves in terms of shape, mass or quantity. So, here we have to find such a line that divides the triangle such that on either side of the line we will have one of the two punched holes and they will be equidistant from the line. In this figure, we can try drawing the line of symmetry through one of the vertices of the triangle.

Complete step-by-step answer:
In the given figure, we can see that there are two black dots, hence they can be used as points of symmetry. We can clearly see that the each pair of dots are at an equal distance from the centre of the triangle as well as the corresponding edges, so we can draw the axes of symmetry as-

These are the required axes of symmetry, and are represented as dotted lines in the plane of the figure.

Note: The most common mistake is that students think that there can be only one axis of symmetry in a figure, which is not true. Infact figures such as circles have infinite axes of symmetry. Hence, students should look for all possible symmetry in the figure.
