5.1 Midsegment Theorem

Here you’ll learn what a midsegment is, and how midsegments in triangles relate to the triangles.

What if you created a repeated design using the same shape (or shapes) of different sizes? This would be called a
fractal. Below, is an example of the first few steps of one. What does the next figure look like? How many triangles
are in each figure (green and white triangles)? Is there a pattern? After completing this Concept, you’ll be able to
better understand how these fractals are created.
