Sigma Maths Workbook 'AS 1.7 Right-Angled Triangles’ is a write-on student resource covering the mathematics students must understand to gain Achieved, Merit, or Excellence in the internally assessed Achievement Standard 1.7 – 'Apply right-angled triangles in solving measurement problems' (AS 91032).

In this workbook students will find clear explanations and detailed worked examples showing the step-by-step processes that will be needed to solve each type of problem, these are followed by a large number of practice exercises and problems of increasing difficulty. At the end of the workbook there are two Achievement Standard Tests. Candidates should use this to evaluate their strengths and weaknesses before the internal assessment.

A full set of answers is included, which acts as a guide to structuring quality answers. An abbreviated version of the Achievement Criteria and Explanatory Notes of the Achievement Standard itself completes the resource. 

The Sigma Workbook 'AS 1.7 Right-Angled Triangles' is best bought before the standard is taught at school and used throughout this time as a classroom and homework resource. Alternatively, the workbook would make an excellent independent study resource in the lead-up to the internal assessment of Achievement Standard 1.7.

Once completed, 'AS 1.7 Right-Angled Triangles' provides a useful set of revision notes at assessment time. It can be kept as a reference book if students intend taking a Year 12 mathematics course.
