GF Position the vertices of the starting triangle with the mouse and press the down arrow. Press the up arrow to repeat.
The sides of the triangle and the perimeter form a geometric sequence with the quotient 0.5 The areas of the triangles form a geometric sequence with the quotient 0.25 The centers of the sides of the triangle are the vertices of the next triangle a, a/2, a/4, a/8........ b, b/2, b/4, b/8,..... c, c/2, c/4, c/8,..... Construction of a triangle and a circle the same as in Sierpinski triangle with two circle https://scratch.mit.edu/projects/722281812/
