In this video, I show how to make a Pythagoras Theorem Working Model using Syringes to push cardboard squares. The three squares 3², 4², and 5² are connected to syringes, and when we push the small syringes, the hydraulic pressure moves the big 5² square.This demonstrates that area of 3² + area of 4² = … Read more
In this video, learn how to make a simple and beautiful real-life Pythagoras theorem model using cardboard, color paper, and basic craft materials.This project shows how a ladder leaning against a wall forms a right-angled triangle and how we can calculate the ladder length using the Pythagorean formula:✔ c² = a² + b² Materials Needed … Read more
This model shows that in a right-angled triangle, the area of the square on the hypotenuse (10 cm) is equal to the sum of the areas of the other two squares (6 cm and 8 cm). Steps to Make the Model https://www.youtube.com/@howtofunda
The best working math models for Class 9 include those demonstrating Pythagorean theorem, circle properties, lines and angles, and polygons. Models using physical representations like squares and triangles for geometry theorems are a great option, while a circular model can illustrate circle properties or a 3D model can showcase polygon 1. Pythagoras Theorem Working Model 2. Coordinate Geometry Plotter … Read more
This model shows corresponding angles. When a transversal cuts two parallel lines, angles in the same position form corresponding pairs. Here, nails act as touch points. When I touch nail 1 and nail 5 together, the circuit completes and the LED glows. That means ∠1 and ∠5 are corresponding angles. Materials Needed Board & Structure … Read more
