Area Of A Trapezium
To derive the area of a trapezium by cutting a triangle at its midpoint.
Mensuration
This interactive model helps students derive the area of a trapezium by fitting triangle pieces into a composite figure.
It shows that a trapezium can be split into a rectangle and two right triangles, making the formula ½ × (sum of parallel sides) × height easy to understand. The visual approach reinforces spatial reasoning, area calculation, and geometric decomposition skills.
