Verify and understand the Pythagoras theorem. Students understand the “how” and “why” of the theorem. They place 3 squares besides right angle triangle and discover by themselves that square of the hypotenuse is equal to the sum of the squares of other two sides.
CHALLENGES IN LEARNING PYTHAGORAS THEORUM:
Memorizing formula and using it to get answer is not enough. Students need to understand why this theorem is only applicable to right angled triangle. Why are they not applicable for acute or obtuse triangle?
WHY PHTHAGORAS THEOREM KIT?
This kit has a right-angle triangle and 3 squares with square grids. Student place the right-angle triangle and three squares besides the three sides of the triangle. Larger square is placed besides the hypotenuse and two squares besides the other two sides of triangle. Now if we count the square grids on the large square and other two small square. We will find that number of squares in large square is exactly same as number of squares in two small squares put together. Hence students can understand the ‘how” of the theorem which is how c2 = a2 + b2. And if students apply this with different types of triangles, they will understand why this is applicable to only right-angle triangle.
