Unit 4 – Geometry | GCSE Foundation Maths Flash Card Bundle
This complete flash card bundle for Unit 4 – Geometry supports Foundation Tier students in mastering key geometric concepts required by the Edexcel IGCSE (Specification A). The flash cards provide targeted practice across all areas of AO2: Shape, Space and Measure, with each sub-topic broken down into 32 clear and accessible questions.
Topics covered in this bundle:
4.1 Angles, Lines and Triangles
Identify and distinguish between acute, obtuse, reflex and right angles
Apply angle properties around a point, on a straight line, and within parallel lines
Understand angle sums in triangles and exterior angle properties
Use angle facts for equilateral, isosceles and right-angled triangles
4.2 Polygons
Recognise and name polygons including quadrilaterals and regular shapes
Calculate missing angles using the angle sum of quadrilaterals and polygons
Apply properties of parallelograms, rectangles, rhombuses, trapezia and kites
4.4 Measures
Use and rearrange the formula: speed = distance ÷ time
Work with compound measures including speed, pressure and density
Apply real-world reasoning to multi-step calculation problems
4.7 Geometrical Reasoning
Give valid explanations and justifications in geometrical problems involving lines, triangles and polygons
Use correct terminology and logical steps in angle and shape problems
4.8 Trigonometry and Pythagoras’ Theorem
Apply Pythagoras’ Theorem in 2D to calculate missing sides
Use sine, cosine and tangent ratios to find lengths and angles in right-angled triangles
Solve contextual problems using trigonometry
4.9 Mensuration of 2D Shapes
Convert between metric units of length and area
Calculate perimeter and area of triangles, rectangles, trapezia and circles
Use formulae for the circumference and area of full and semicircles
4.10 3D Shapes and Volume
Recognise and describe 3D solids including cube, cuboid, prism, pyramid, cylinder, sphere and cone
Identify and define the properties of faces, edges and vertices in 3D shapes
This bundle is ideal for revision, independent learning, classroom starters, or intervention sessions. Each section reinforces both conceptual understanding and procedural fluency in a wide range of geometry problems.
