Build Geometry Skills with Geometry Builder
A hands-on way to practise angles, triangles, quadrilaterals, perimeter, area and symmetry.
The Geometry Builder game lets students construct and measure shapes directly on screen. Drag points to build exact angles, triangles and quadrilaterals, rotate a symmetry line into place, or type in the result for perimeter and area challenges, earning points for every correct build and bonus points for precise construction and streaks.
Five challenge types in one game
Angle Builder asks you to drag an arm until it makes a target angle such as 60° or 90°. Triangle Builder challenges you to construct equilateral, isosceles or right-angled triangles. Quadrilateral Builder asks for squares, rectangles or parallelograms. Perimeter & Area tests calculations such as the area of an 8 cm × 5 cm rectangle (40 cm²) or the perimeter of a square. Symmetry asks you to draw a true line of symmetry across a square, rectangle or isosceles triangle. In Mixed mode every builder appears at random.
Fit geometry into the CBSE routine
Geometry runs throughout the CBSE Mathematics curriculum, from basic shapes in Class 6 Maths to triangles and circles in Class 9 Maths and Triangles and Circles in Class 10. Pair the game with Class 10 Coordinate Geometry notes and our full CBSE study material, or explore the other Maths games we have built.
