Geometry

Question Analysis:
This question requires calculating the midpoint of side QR in triangle PQR using the midpoint formula.
The focus is on proper application of the formula to given coordinates.

Key Concept Explanation:
The midpoint formula finds the exact center point between two coordinates by averaging their x and y values separately.

Step-by-Step Solution:
Given Q(8, 7) and R(6, 1):
Midpoint = ((8 + 6)/2, (7 + 1)/2) = (7, 4)

Common Mistakes:
Students often average x and y coordinates together or miscalculate simple arithm...
