Similarity & Congruence: GCSE / IGCSE

These GCSE / IGCSE similarity and congruence lessons connect geometric reasoning with scale-factor relationships in 2D and 3D. Topics include:

  • Congruence: proving triangles are congruent using angle properties and geometrical facts
  • Calculating missing lengths in similar shapes using the length scale factor
  • Similar areas: linking length and area scale factors to solve problems with similar 2D shapes
  • Similar shapes calculations: using length, area and volume scale factors in more complex problems, including similar 3D objects
  • Volume of similar shapes and the volume scale factor, including working with similar solids and related capacities
