The image appears to be 200 cm away from us, i.e., 100 cm on the other of the mirror. And if we move towards the mirror, the image moves closer to us and to the mirror, but the size remains the same.

(a) Yes, with one line of symmetry we have the triangle: This is an isosceles triangle. (b) No, as there exists no triangle with only two symmetry lines. Hence, no such triangle is possible. (c) Yes, a triangle with three lines of symmetry is possible: And it is an equilateral triangle, shown below in the figure. (d) Yes, the triangle with no line of symmetry is possible and it is a scalene...

From the figure we can say that line  is the mirror line. Because, when the figure is completely folded about the line  then the left part is covered by the right part completely.

We can observe that the angle of rotation is the factor of ,then it will have rotational symmetry of order more than 1. (i)  is a factor of  so the figure having its angle of rotation as  will have rotational symmetry of order more than 1. (ii) is not a factor of  so the figure having its angle of rotation as  will not have rotational symmetry of order more than 1.
 After rotating by    about a centre, a figure looks exactly the same as its original position, then it will look symmetrical on rotating by  All angles are multiples of .
