Homework Help: Geometry

Posted by Amy on Sunday, November 30, 2008 at 1:39pm.

Do the altitudes of an isosceles triangle go to the midpoints of the opposite sides?

My triangle ABC is isosceles with points A (0,0), B (a,b), and C (2a,0). My diagram shows that the altitude from A will hit side BC at point N and the altitude from C will hit side AB at point M, but I can't find anywhere in the book if M and N are supposed to be midpoints. Help?

Thanks,
Amy :)
