On a plain sheet of paper:

Draw 3 points of a triangle

Find the midpoints of each side

Link the midpoints ; In the codes

Paint the midpoint triangle blue. How many triangles are there?

Find the midpoints of the smaller triangles

Link them

Paint the midpoints of smaller triangles blue. How many triangles are there now How many triangles are not blue

what happens when you repeat the process n times?

Write a pseudocode/algorithm for the iterations

write an html code to display the image
