Geometry

Question Analysis:
This question uses coordinate geometry to find a midpoint of a diagonal.
The main focus is calculating the midpoint between two vertices.

Key Concept Explanation:
In a parallelogram, diagonals bisect each other.
So, the intersection point of diagonals is the midpoint of both.

Step-by-Step Solution:
Midpoint formula:
N = ((x₁ + x₂)/2, (y₁ + y₂)/2)
= ((2 + 10)/2, (1 + 9)/2) = (12/2, 10/2) = (6, 5)
