i haven't done a geometry proof in forever.
and we got one to for homework and i was wondering if someone smart here could help me.
heres the question:
The vertices of DEF triangle are D(-3,4), E(-1,-2), and F(3,2)
A) find an equation of the altitude from vertex D of triangle DEF
B) is the altitude from D also the median from D? explain your answer.
C)prove that triangle DEF is isosceles
mad karma for the answer to this. i feel so dumb right now. i should know how to do this. brain fart.
