Asit Das Gupta and Alok Kumar Solutions for Exercise 1: EXERCISE 9

State whether a triangle $ABC$ whose sides $AB=AC= 6 \mathrm{cm}$ and $BC=5 \mathrm{cm}$ is symmetric or not. If symmetric mention the number of lines of symmetry.

State whether a Rectangle is symmetric or not. If symmetric mention the number of lines of symmetry.

State whether a Square is symmetric or not. If symmetric mention the number of lines of symmetry.

State whether a Circle is symmetric or not. If symmetric mention the number of lines of symmetry.

State whether a segment of a circle is symmetric or not. If symmetric then mention the number of lines of symmetry.

Trace the following figures and verify by folding the paper whether the line $l$ is a line of symmetry

If the points $A$ and $B$ are symmetric with respect to line $l$ then write the relation between line segment $AB$and the line $\mathit{l}$.

In the adjoining figure, the point $B$ is the reflection of point $A$ in the reflecting line $m$ then line $m$ is called _____ .
