Year 7, Unit 6 – triangles and quadrilaterals
This 11-lesson unit addresses content from the focus areas of Angle relationships and Properties of geometrical figures.
Students develop the language, knowledge and understanding to classify these 2-dimensional shapes according to their geometrical properties and apply this to meaningfully make connections across topics and concepts.
The Mathematics K–10 Syllabus (2023) is to be taught in Years 3 to 10 from 2024.
Detailed implementation information including key features and resources is available on the Mathematics syllabus development page (NESA).
