Question

TRIANGLES
Theorem 6.2 : If a line divides any two sides of a
triangle in the same ratio, then the line is parallel
to the third side.
D
This theorem can be proved by taking a line DE such
AD AE
that
and assuming that DE is not parallel
DB EC
to BC (see Fig. 6.12).
If DE is not parallel to BC, draw a line DE
parallel to BC.
B
AD
AE'
Why?)​

Answer 1

Answer:

because you don't know that all lines that you draw is going to be exact parallel. moreover some things you have to prove in maths in that case I can draw AD = AB.....by scale and say that was the part of construction. understood??? we can't just say things that is why we have to take the general condition that line is not parallel..then prove it parallel and so on
