Fractal geometry

This week we took two fractals and we found the total length of them. Practice with these two fractals:

Sample new questions:

1. This fractal rule for the fractal Cantor dust is: take out the middle third or each segment in the previous iteration.

A. Draw the next iteration of the fractal

iteration 0
iteration 1
iteration 2
iteration 3  

B. Complete the table below, and explain your rule for finding the numbers that go in the table

iteration number number of pieces length of each piece total length
0 1 1 1
1 2 1/3 2/3
2      
3      
n (formula)      

 

2. The fractal rule for this fractal (this one doesn't have a name) is: take out the middle third, and replace it with the top 3/4 of a square:

Segment was:

Changed to:

This one's a little hard to visualize, so I have color coded a version to help you see the change from iteration 1 to iteration 2:

Iteration 1 is:

Iteration 2 is:

 

A. Draw iteration 3

iteration 0
iteration 1
iteration 2

B. Complete the table below, and explain your rule for finding the numbers that go in the table

iteration number number of pieces length of each piece total length
0 1 1 1
1 5 1/3 5/3
2      
3      
n (formula)
