Pythagoras Theorem Model

According to Pythagoras Theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

This working Model represents this Theorem.

Step 1: Material Required

PVC Material

Cardboard

Thread

Screws

4 bobbins

Paint

Colourful Papers

Graph Paper

Glue, etc.

Step 2: Construction of the Frame

The frame of the model is made of PVC pipe and elbows, which is connected together to make L-type frame.

This represents a 90 degree angled frame.

It consist of Two PVC pipe of 30 cm each and two elbows, one is L-type and other is T-type.

I have painted them with different colours.

And for the Base, I used a cardboard (size 34 cm X 15 cm), which is covered with colourful Papers.

Step 3: Scales

The scales are made of two strips of cardboard paper (total = 6) and graph paper strips and markings on them with pen.

Total Three scales are used, for X-axis (Base), Y-axis (Perpendicular) and other moving scale (Hypotenuse).

For moving along X-axis, a circular slider is used and For the Y-axis a piece of PVC pipe is used with a small piece of cardboard.

Step 4: How It Works!

For sliding purpose 4 bobbins are used.

2 bobbins for the slider of X-axis and other 2 bobbins for the slider of Y-axis.

Thread is bent along the bobbins which is glued with the sliders of each axis.

By rotating Bobbins the slider can be moved in to and fro translational motion.
