Key Topics to Revise
Ratio of Areas of Two Triangles
- The ratio of areas of two triangles equals the ratio of products of their bases and corresponding heights
- When heights are equal, area ratio equals base ratio
- When bases are equal, area ratio equals height ratio
Basic Proportionality Theorem (Thales' Theorem)
- If a line is parallel to one side of triangle, it divides other two sides proportionally
- The converse is also true: if a line divides two sides proportionally, it's parallel to third side
- This theorem forms the foundation for similarity concepts
Angle Bisector Property
- Angle bisector divides opposite side in ratio of adjacent sides
- Internal angle bisector creates internal division
- This property helps solve many triangle problems
Three Parallel Lines and Transversals
- Three parallel lines cut by two transversals create proportional segments
- Ratios of corresponding segments on different transversals are equal
- This property extends basic proportionality to multiple parallel lines
