Congruence and similarity in geometry

Geometry and measures • Mensuration and calculation

Key concepts

What you'll likely be quizzed about

  • Congruent figures are identical in shape and size.
  • If one figure can be transformed into another by rotation, reflection, or translation, they are congruent.
  • Examples include two triangles that can perfectly overlap when one is moved without resizing or reshaping.

Congruence can be tested through methods like SSS, SAS, and AAS in triangles.

Key notes

Important points to keep in mind

Congruent shapes can be overlapped exactly.

Similar figures have proportional sides and equal angles.

Transformations can help establish congruence.

Use scale factors to compare similar figures.

Check angles for determining similarity.
