Imagine cutting a triangle with a line PARALLEL to its base what happens to the smaller triangle created? Avinto reveals Tanzania Form Two's most powerful geometry theorems: the Basic Proportionality Theorem and its applications! These theorems are the backbone of architectural design, road planning, and even computer graphics! When a line is parallel to one side of a triangle, it splits the other two sides in EQUAL proportions and knowing this ONE rule unlocks dozens of problems! Prepare to see triangles in a completely new way. Your geometry game is about to level up! Let's prove it!
