Step 5 |
Calculation:
Draw an equilateral triangle with side length of
Figure-1
To the middle third of each of the sides of this seed, add an equilateral triangle with sides of length 27 cm. The result is a 12 sided snowflake with perimeter,
Figure-2
To the middle third of each of the 12 sides of snowflake add an equilateral triangle with sides of length one third of the length of the side. The result is a snowflake with 48 sides each side length of 9 cm and the perimeter is,
