Stage 5

Properties of geometrical figures B (Path)

Stn (Standard), Adv (Advanced) and Ext (Extension) have been used to suggest paths for related Stage 6 courses.

Identify and explain congruence
  • Identify figures as congruent figures if translations, reflections and rotations can move one figure exactly on top of another

  • Match the sides and angles of 2 congruent polygons

  • Determine that having equal radii is the condition for 2 circles to be congruent

Develop and use the conditions for congruent triangles
  • Establish the 4 congruence tests for triangles (SSS, SAS, AAS and RHS)

  • Use the congruence tests to identify a pair of congruent triangles from a selection of 2 or more triangles

Develop and apply the minimum conditions for triangles to be similar
  • Examine the minimum conditions needed and establish the 4 tests for 2 triangles to be similar

  • Apply the minimum conditions needed and determine whether 2 triangles are similar using an appropriate test

Establish and apply properties of similar shapes and solids
  • Solve problems involving areas and volumes of similar shapes and solids

Apply logical reasoning to numerical problems involving plane shapes
  • Apply geometrical facts, properties and relationships to find the sizes of unknown sides and angles of plane shapes in diagrams, providing appropriate reasons

  • Define the exterior angle of a convex polygon

  • Apply the result for the sum of the interior angles of a triangle to find, by dissection, the sum of the interior angles of a polygon with more than 3 sides

  • Apply the results for the interior and exterior angles of polygons to solve problems involving polygons
