Geometry

Question Analysis:
This problem applies the midsegment theorem to parallelograms, requiring understanding of how midpoints divide the figure.

Key Concept Explanation:
In a parallelogram:
The segment connecting midpoints of opposite sides is parallel and equal in length to the other two sides
This midsegment divides the parallelogram into two smaller, congruent parallelograms

Step-by-Step Solution:
Visualize the parallelogram with midpoints M and N
Understand that MN will be parallel and equal in length to both PS and QR
Since MN = 14 cm, QR must also be 14 cm

Common Mistakes:
Assuming the midsegment is half the length of sides
Confusing which si...
