[GRADE 8] Geometry of 2D shapes(Classifying 2D shapes)
In this lesson, we’re stepping into the world of 2D shapes the flat figures that form the foundation of geometry. From triangles to trapeziums, we’ll learn how to classify, describe, and compare these shapes based on their properties.
You’ll explore:
🟣 Types of 2D shapes: triangles, quadrilaterals, circles, polygons
📐 Classifying shapes: based on sides, angles, symmetry, and parallel lines
🔺 Properties of triangles: equilateral, isosceles, scalene, right-angled
🟦 Properties of quadrilaterals: square, rectangle, rhombus, parallelogram, trapezium
🔄 Symmetry and angles: identifying lines of symmetry and angle relationships within shapes
🧠 Using diagrams to solve problems: applying properties to find missing sides or angles
📌 These skills help you build strong diagram-based reasoning and prepare you for more advanced geometry in Grade 9 and beyond.
💡 You’ll learn how to label shapes, compare features, and use geometry language to explain your thinking clearly.
So grab your geometry set, open your eyes to the shapes around you, and let’s classify the world one angle, one side, and one shape at a time.
