Define congruence of plane shapes using transformations

Elaborations

• understanding the properties that determine congruence of triangles and recognising which transformations create congruent figures (Skills: Numeracy, Critical and Creative Thinking)
• establishing that two figures are congruent if one shape lies exactly on top of the other after one or more transformations (translation, reflection, rotation), and recognising that the matching sides and the matching angles are equal (Skills: Numeracy, Critical and Creative Thinking)
