Explanation:
To find the distance between two points, we have to use the distance formula:

Let's solve for line PQ first. We plug in the points into the formula and solve from there.
P: (-5, 1)
Q: (-2, -5)





Now, let's solve line ML.
M: (5, 3)
L: (2, -3)





Answer: 3√5, 3√5, yes, they are congruent.
