Geometric reasoning

Based on the Australian Curriculum, Geometric reasoning in Mathematics Year 7 includes:

• ACMMG163 Identify corresponding, alternate and co-interior angles when two straight lines are crossed by a transversal
• ACMMG164 Investigate conditions for two lines to be parallel and solve simple numerical problems using reasoning
• ACMMG166 Demonstrate that the angle sum of a triangle is 180° and use this to find the angle sum of a quadrilateral
• ACMMG165 Classify triangles according to their side and angle properties and describe quadrilaterals
