Triangles – Exercise 6.2 Description

Exercise 6.2 focuses on the Basic Proportionality Theorem (BPT), also called Thales' Theorem.

What you learn in this exercise:

The statement of Basic Proportionality Theorem:

If a line is drawn parallel to one side of a triangle and it intersects the other two sides,
then it divides those two sides in the same ratio.

Understanding how a parallel line inside a triangle creates proportional segments.

How to apply BPT to solve problems involving triangles.

Numerical problems where you have to find unknown side lengths using ratios.

Simple proof-based questions based on triangle ratios.

Key Idea

If a line ‖ (parallel to) one side of a triangle cuts the other two sides, then the two sides are divided proportionally.

This exercise builds the foundation for solving many triangle problems using ratios and proportionality.
