Question

Is it possible for the perimeter of a figure to change after its reflected?

Answer 1

Alright, lets get started.

Please refer the diagram I have attached.

There is a triangle ABC having co-ordinates (1,3), (5,2) and (4,-1)

When we make a reflection of this triangle names A'B'C', the co-ordinates are changed (-1,3), (-5,2) and (-4,-1)

But the length of each side remains same.

So, if the length of each side will remain same after its reflected, so perimeter will also be same.

So,after reflection, the perimeter of a figure is not changed. : Answer

Hope it will help :)

Answer 2

No, reflections do not chage shape, size or area. The only transformation that does that is dilation.
