Problem 4

How many triangles are in this figure? (Some triangles may overlap other triangles.)

$[asy] draw((0,0)--(42,0)--(14,21)--cycle); draw((14,21)--(18,0)--(30,9)); [/asy]$

$\text{(A)}\ 9 \qquad \text{(B)}\ 8 \qquad \text{(C)}\ 7 \qquad \text{(D)}\ 6 \qquad \text{(E)}\ 5$

By inspection, we have that there 5 triangles.

$\boxed{E}$
