 Hello all and welcome to the session. Today the question is draw the lines of symmetry of the following figure and also mark the point of symmetry if any. Now before starting the solution of the question we should know about some results of symmetry. First is line of symmetry. The line about which the figure may be folded so that the two parts of the figure will coincide and second is the point of symmetry. If every line segment of the figure to the point is bisected by the point that line is called the point of symmetry. So this will work as a key idea for solving out this question and now we will start with the solution. Now here for this figure we have to find out the lines of symmetry. Now according to the definition which is given as a key idea the line of symmetry is a line about which the figure may be folded so that the two parts of the figure will coincide. Now here n is the line of symmetry of the given figure because if along this line the figure is folded then the two parts will coincide. The line m is also the line of symmetry of the given figure as along this line also if the figure is folded then the two parts will coincide with each other. Therefore we can write that the lines in an m are the lines of symmetry of the given figure and now we have to find the point of symmetry. Now according to the definition which is given as a key idea if every line segment of the figure passing through the point is bisected by the point that line is called the point of symmetry. Now here we can see the point o. Now the point o here is the point of symmetry since the lines having passed through these points are bisected by the point o. Therefore point o is the point of symmetry of the given figure. So this is the solution of the given question and that's all for this session. Hope you all have enjoyed the session.
