Apply logical reasoning, including the use of congruence and similarity, to proofs and numerical exercises involving plane shapes

Elaborations

• distinguishing between a practical demonstration and a proof (for example demonstrating triangles are congruent by placing them on top of each other, as compared to using congruence tests to establish that triangles are congruent) (Skills: Numeracy, Critical and Creative Thinking)
• performing a sequence of steps to determine an unknown angle giving a justification in moving from one step to the next. (Skills: Numeracy, Critical and Creative Thinking)
• communicating a proof using a sequence of logically connected statements (Skills: Literacy, Numeracy, Critical and Creative Thinking)
