Question

In figure if DE 8cm, DEll BC and D is the mid point
of AB, then the true statement is
(1) E is the mid point of AC
(2) AB=BC
(3) DE = BC
(4)DE and BC meet at same point il we extend both
of them indefinitely.​

Answer 1

Answer:

Given: D and E are mid points of AB and BC respectively. DF∥BC

Since, DF∥BC D is mid point of AB.

By converse of mid point theorem, F is mid point of AC.

Now, E and F are mid points of BC and AC respectively.Thus, by mid point theorem,

EF∥AB or EF∥DB

Since, opposite sides are parallel to each other. Hence, DBEF is a parallelogram.
