When a shape is rotated, it must be rotated over a line.
<em>The square must be reflected over line </em>
<em>, for it to be mapped onto itself.</em>
<em />
<u>The points are given as:</u>




To map the square onto itself, it must be reflected over its diagonal
The diagonals of the square are: AC and BD
<u>Using AC, we have:</u>
---- 
---- 
Start by calculating the slope (m)

So, we have:



The equation is then calculated as:

This gives:



Rewrite as:

So, the square must be reflected over line
, for it to be mapped onto itself.
See attachment for square ABCD and its line of reflection.

Answer:
13 cms
Step-by-step explanation:
By Pythagoras:-
x^2 = 12^2 + 5^2
x^2 = 144 + 25
x^2 = 169
x = √169
= 13
