Thanks - blahblahblah1234

note that the area of a triangle is $\displaystyle A = \frac{1}{2}bh$

if $\displaystyle h$ is an altitude, then $\displaystyle b$ is the side perpendicular to that altitude

so ...

$\displaystyle \frac{1}{2} b_1 h_1 = \frac{1}{2} b_2 h_2$

if $\displaystyle h_1 = h_2$ , what does that say about the lengths of the two corresponding sides, $\displaystyle b_1$ and $\displaystyle b_2$ ?

further ... what kind of triangle would this be, and what can you say about the lengths of the medians to these two corresponding sides?

Thanks skeeter, haha. Soo the triange would be isoceles or equilateral and the medians would be congruent to the altitudes. Thanks again.
