6. In this
diagram, nine
congruent triangles
fit together to form a
larger triangle that is
similar to the smaller
triangles.
a) How many different similar triangles
can you find in the diagram?
b) Try this design with a different-
shaped triangle. Do you think it can be
done for any triangle?
c) Can you do it with a different number
of smaller congruent triangles? Try it
with two, three, and four congruent
. triangles.
