Geometry STEM Challenge 1600: When Cevians Cross: Find the Missing Area
Explore the power of geometric reasoning in this STEM-focused challenge. Cevians intersect, areas are revealed, and one remains hidden. Can you apply your problem-solving skills to uncover the missing piece?
Problem Statement 1600
In triangle ABC, cevians AD and CE intersect at point O. If the areas of triangles AEC, ADC, and BEO are 10, 7, and 3, respectively, determine the area of triangle BOD.

📌 Problem Statement
In triangle ABC, cevians AD and CE intersect at point O. If the areas of triangles AEC, ADC, and BEO are 10, 7, and 3 respectively, determine the area of triangle BOD.
📌 A Geometric Mindfulness Exercise
Close your eyes. Imagine △ABC as:
A galaxy (O = black hole, cevians = gravitational pulls).
A neural network (areas = activation weights).
A city map (△BOD = a park’s unknown foot traffic).
🌍 Real-World Analogy
Imagine designing a city or a network. Paths intersect and define spaces. Some zones are measured, others hidden. This triangle represents any complex system — where the unknown can be inferred from the known.
📚 A STEM Meditation on Knowledge
Mathematics is a language that reveals invisible structures. In every triangle, there is a history of measurement, order, and relationship. Solving for the unseen is how humanity has always advanced.
