huh... i also askd dis question... bt no answer was der...:(
Cut out any 4 sided straight lined shape and the 4 interior angles will always add up to 360 degrees.
You can use pythagoras working model
you should try a Pythagoras theorem in which you can show the volume of cone is 1/3 of the volume of a cylinder (both having same h and r) or you can try to make simple models of cube,cuboid,sphere,cone,cylinder,square and triangular pyramids and then can explain that how to find the area,perimeter,volume,faces,sides etc. other than these you can also try to make a geoboard. all the best!

It depends on which model you are using
you can make a working model of any polygons. first,draw any polygons (triangle,pentagon,hexagon etc....)and also draw its interior angles and exterior angles (note the polygons sum of the angles). then cut its exterior angles.then bring the all exterior angles(after the cut) togather.now you can make a circle. its means , the sum of the exteriorangles of any polygon =sum of the angles of a circle (360 degree = 360 degree)
Shine a laser pointer onto mirrors set up at various angles.
I can give you several sentences.The two roads run parallel to one another for several miles.The scientist traveled to a parallel dimension.Two parallel lines will never meet.
First take a peice of cardboard then you can make your own houses with staght angles no curves and stick it
