The answer is -4 while the element is chlorine
The equation
shows that the diagonals are congruent perpendicular bisectors.
The vertices of the square are given as:
- c = (1,1)
- d = (3,1)
- e =(3,-1)
- f = (1,-1)
<h3>How to determine the
congruent perpendicular bisectors.</h3>
Start by calculating the slope of diagonal ce using:

So, we have:



Next, calculate the slope of diagonal df using:

So, we have:



The slopes of both diagonals are:


By comparing both slopes, we have:

i.e.

Hence,
shows that the diagonals are congruent perpendicular bisectors.
