Question

___ of a triangle device it into 2:1 ratio....plz guys help me in this .....​

Answer 1

Answer:

Let DD be a point on BC¯¯¯¯¯¯¯¯BC¯ between BB and CC. Observe that △BDA△BDA and △DCA△DCA have the same height, 3−(−1)=43−(−1)=4. Let x=|BD|x=|BD| and y=|DC|y=|DC|. The area of △BDA△BDA is 2x2x, the area of △DCA△DCA is 2y2y, and x+y=|BC|=2x+y=|BC|=2, so y=2−xy=2−x. Now all you have to do is find xx so that 2(2−x)=2(2x)2(2−x)=2(2x).
