Statment: Let a, b and c be nonnegative real numbers, and let A=(0,0), B=(a,b), and C=(c,0) be points in the coordinate plane, such that AB=AC. Let D be the midpoint of line BC, let E be the foot of the altitude from D to line AC, and let F be the midpoint of line DE.

 

What I don't get: 'Let D be the midpoint of line BC, let E be the foot of the altitude from D to line AC'. 

 

I don't really understand what they mean by that, if possible, could you please draw a sketch of it really quickly? 

 

Thank you so much!!!
