Difficulty: Medium
Correct Answer: 6 sq cm
Explanation:
Introduction / Context:
Medians of a triangle intersect at the centroid, partitioning the triangle into six smaller triangles of equal area. Recognizing this partition lets us read off areas of sub-triangles like ΔCGE directly.
Given Data / Assumptions:
Concept / Approach:
Centroid divides the triangle into six equal-area small triangles formed by the three medians. Thus each small triangle has area (total area)/6.
Step-by-Step Solution:
Verification / Alternative check:
Draw medians; around each vertex, two small triangles meet; all six are congruent in area by symmetry and midpoint properties.
Why Other Options Are Wrong:
Common Pitfalls:
Forgetting that three medians create 6, not 4, parts; confusing centroid 2:1 segment property with area partition.
Final Answer:
6 sq cm
