The basic triangle that starts the construction.
Three basic triangles will combine to make the first stage of Sierpinski triangle.
First stage.
Three first stage triangles combine to make a second stage triangle.
Three second stage triangles combine to make a third stage.
Mathematicians building the third stage.
Check - is this a third stage triangle?
Starting to combine 3rd stage triangles into the 4th stage.
The 4th stage is almost done!
The thrill of victory - success in constructing a 4th stage Sierpinski triangle!
