What’s This Exercise All About?

This exercise is based on the Basic Proportionality Theorem (also called Thales Theorem) which says:

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



This is a super important concept to understand similar triangles and forms the base for many questions in the chapter!



Must-Know Tricks:

✅ Check if a line is parallel before applying BPT.
✅ Use cross-multiplication to compare ratios easily.
✅ For reverse cases, apply converse of BPT.
✅ Show proper steps with reasons for full marks in exams.
✅ Practice with diagrams for better understanding!
