Question

In the figure, ABC is an equilateral triangle. D,E and F are the mid-points of AB, BC and Ac respectively.

Answer 1

\[How \to prove that, DF \parallel BC and DF = 1/2 BC ?\]

Answer 2

\[\Delta ABC =1/2 \Delta EDF, AB=1/2ED, AC=1/2EF \]
AND so DF // to BC

Answer 3

I recommend to use \(\Large\color{black}{ \bf \text{~} }\) for space.
You can put up \(\Large\color{black}{ \bf \text{~~} }\) this will give you more space.
You can put any amount of \(\Large\color{black}{ \bf \text{~} }\) and the more you put the bigger the space \(\large\color{black}{ \bf \text{:)} }\)
