 Hi and how are you all today? My name is Priyanka and the question says, complete the hexagonal and star-shaped rangolis, C figure 7.53 first and second that will be downstairs, by filling them with as many equilateral triangle off side 1 centimeter as you can. Count the number of triangles in each and answer which has more triangles. Now this is an interesting question of drawing triangles. Now these are the two rangolis that is given to us. Now let us first fill up this rangoli. The all the sides of this hexagonal shaped rangoli is of 5 centimeters and we need to draw equilateral triangle of side 1 centimeter each. So what we need to do is we need to take the base each and every base that is 5 centimeter each and we need to draw equilateral triangles like this. Now if you carefully analyze and notice this is a 5 centimeter shape so you will be having 5 triangles in this base like this. Like this for each and every base you will need triangles like this in this rangoli and similarly in this rangoli also you will be making equilateral triangles. This is the first triangle that you have made then you have two triangles inside each and every. So one two three four triangles here and likewise you will be making it for each and every column four here four here and all and then inside also and following this pattern you will find out how many number of triangles can be made in this rangoli and in this rangoli and then you will be telling me the answers right. So enjoy drawing all the triangles that are equilateral triangles of 1 centimeter in these rangolis and enjoy this activity. I hope you enjoyed and understood what you need to do. Bye for now.
