Match the following shapes with their number of lines of symmetry. i Square a No line of symmetry ii Parallelogram b One line of symmetry iii Isosceles triangle c Two lines of symmetry iv Rectangle d Four lines of symmetry

We know that, If a line divides a given figure into two identical halves then we say that the given figure is symmetrical about that line and the line is called the line of symmetry. For i The figure is symmetric along the 2 diagonals and 2 midpoints of opposite sides as shown below Thus, it has four lines of symmetry. Hence, i → d For ii Consider the parallelogram A B C D , We are not able to fold this figure along any line, in such a way that the two halves are mirror images of each other Thus, it has no line of symmetry . Hence, ii → a For iii The figure is symmetric along its bisector of the vertical angle i.e., along the median X L . Thus, it has one lines of symmetry. Hence, iii → b For iv Consider the rectangle P Q R S , The figure is symmetric along the lines l and m joining the midpoints of opposite sides. Thus, it has two lines of symmetry. Hence, iv → c Answers i Square d Four line of symmetry ii Parallelogram a No line of symmetry iii Isosceles triangle b One lines of symmetry iv Rectangle c Two lines of symmetry
