Year 12 Measurement addresses outcomes from the Measurement and Geometry Strand contained in the NSW General Senior Syllabus. Students who study Year 12 Measurement apply estimation of quantities to achieve appropriate levels of accuracy to particular situations relating to measurement. In addition, students apply understanding of length, area, volume, similarity and trigonometry to a variety of problems.
This learning program is made up of the following 6 topics, broken down into 74 concepts.
