you can make a working model on pythogoras theorem.u will need glass sheet,beads,a strong card board,thermocol and small sticks,
1st take the card board n draw a right angled triangle on it then drw squares with sides same as dat of d triangle adjoining 2 d figre.
then cut out d figure frm thermocol n paste it d remaining on the card board
then paste d small sticks such that d beads can move from one square 2 d othr.then fill beads in d smallr squares then covr the whole with d glass sheet.
when we shke it v find dat d beads in d smaller squares will correctly fit in d bigger one that is d square with d hypotenuse as its side.thus v can say hypotenuse^2=altitude^2 + base^2
