Is it possible for the perimeter of a figure to change after its reflected?
2 answers:
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:
This is the interval from -9 to 16. Exclude -9 but include 16.
=====================================================
Work Shown:
The idea is to multiply all sides by 5, then add 1 to all sides
This converts to the interval notation
note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
