This type of problem solving goes from where a person does not have the solution to a problem to suddenly having the solution.
<h3>What is Insight problem solving?</h3>
This problem solving skill is one that occurs when the person that is involved suddenly moves from not being able to have answers to a problem, to suddenly being able to solve it.
- This moment is important because it helps to signify the end of a long standing problem through the discovery of a new idea and understanding.

The answer is the last one d
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.
