Year 8 · Maths
Interpret mathematical relationships algebraically and geometrically in Year 8 Maths
Start here
Focus on Pythagoras theorem and similar shapes. Open support for “Calculate Missing Sides in Similar Shapes”, then explain the idea in your own words.
Year 8 learners practise pythagoras theorem and similar shapes.
The activities include Calculate Missing Sides in Similar Shapes, Calculate the Hypotenuse of a Right-Angled Triangle, Calculate the Length of a Line on a Graph Using Pythagoras' Theorem, and related practice. The checked support below includes practice, teach, worksheet, video. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
