Key Topics to Revise

1

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
2

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
3

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
4

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
