# Mathematics / Year 10 / Measurement and Geometry / Geometric reasoning

Curriculum content descriptions

Apply logical reasoning, including the use of congruence and similarity, to proofs and numerical exercises involving plane shapes (ACMMG244)

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)
• performing a sequence of steps to determine an unknown angle giving a justification in moving from one step to the next.
• communicating a proof using a sequence of logically connected statements
General capabilities
• Numeracy Numeracy
ScOT terms
