Complete the hexagonal rangoli and the star Rangolies (see Figs. ) by filling them with as many equilateral triangles of side 1 cm as you can. Count the number of triangles in each case. Which has more triangles ?

Can you write the rule for making pattern for F? Table given below gives the number of match sticks required to make a pattern of Fs.

Take identical cut outs of congruent triangles of sides 3 cm ,4cm , 5cm Arrange them as shown . You get a trapezium (check if) which are the parallel sides here ? should the non -parallel sides be equal ? You can get two more trapeziums using the same set of triangles. Find them out and discuss their shapes.
