Answer:
Intersection is what they both have in common.
In this case intersection of E and B is 3 and 8.
While the union is both of them added together.

Step-by-step explanation:
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.

Use the pythagorean theorem. So 4^2 + 7^2 = 10^2. Simplify to 16+49=100. This simplifies to 65=100 which is not true so these sides cannot make a triangle.
