Answer Expert Verified Given, DE || AB and DE is drawn from the mid point of BC i.e.D, then by converse of mid-point theorem, it bisects the third side which in this case is AC at E. Therefore, E is the mid point of AC. Hence, BE is the median of ΔABC.

The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c). Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).

Find formulas for the circle's radius, diameter, circumference and area , in terms of 'a'. As we've shown above, the circle's radius is equal to the half the length of the square's side, so r=a/2. The diameter is twice the radius, so d=a. The circumference is d ·π, so C=πa.
