Question

3. In fig if DE = 8 cm, DE || BC and D is the mid-Point of AB, then the true statement is
A Compte
em
a. E is the mid-Point of AC
b. AB = BC
C. DE = BC
d. DE and BC meet at some point if we extend both of them indefinitely.​

Answer 1

Answer:

a ) E is the mid point of AC

Answer 2

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.
