Let consider A(3,5), B(6,4) and C(3,−2),
d : x−5y+7=0
Consider a dot D such as ABCD is a trapezium
and (AD) and (BC) are parallel lines.
Q1) Give the equation of the line which
contains the point D.
Q2) Considering that the trapezium
should be convex, are all the points D of
the lines correct for the Trapezium ?
Which ones are ?
Give a proof.
I have some difficulties to anzwer the
question n°2, could someone please,
help me.
Thank you.
