ured: Cardboard, geometry box, coloured paper, white drawing sheet, sken
Objective: To verifi
Materials Requi
scissors, glue.
Procedure:
1. Take a rectangul:
White drawing sheet, sketch pens, a pair of
rectangular piece of cardboard and use it as a baseboard,
congruent quadrilaterals from the white drawing sheet.
2. Cut two congruent au
3. Colour the for
hur the four angles of both the quadrilaterals with different colours after drawing circular arcs o
radius, as shown in figure (a).
Paste one of the quadrilaterals on the baseboar
laul laterais on the baseboard and cut the four coloured angles from the ou
e the cut outs of angles of the quadrilateral in such a way that the four vertices coincide at a points
by forming a complete angle at the point O, as shown in figure (b).
5. Place the cut out​
