A kite in the shape of a square with a diagonal 32 cm and an isosceles triangle of base 8 cm and sides 6 cm each is to be made of three different shades as shown in figure. How much paper of each shade has been used in it? Solution: Each shade of paper is divided into 3 triangles i. For triangle II: Since, diagonal of a square divides it into two congruent triangles.
