Naming triangles, quadrilaterals and polygons
MA26-01
This lesson is coming soon.
In this lesson
Name special triangles, special quadrilaterals and regular polygons correctly, especially telling visually similar shapes like kites and rhombuses apart.
What it covers
- Names of special triangles: scalene, isosceles, equilateral, right-angled
- Names of special quadrilaterals: square, rectangle, parallelogram, trapezium, kite, rhombus
- Names of regular polygons: pentagon, hexagon, octagon, decagon
- A side-by-side comparison table for the visually similar shapes (kite vs rhombus vs parallelogram)
Key words
For: OCR GCSE J560, Edexcel IGCSE 4MA1, AQA GCSE 8300, Edexcel GCSE 1MA1, Eduqas GCSE C300, Cambridge IGCSE 0580

For teachers
This GCSE Maths lesson teaches naming triangles, quadrilaterals and polygons. By the end, students should be able to name special triangles, special quadrilaterals and regular polygons correctly, especially telling visually similar shapes like kites and rhombuses apart. It works through two worked examples and the mistakes examiners report.
