# Help with Olympiad problem , geometry [closed]

I need a graph of this problem?

In a rhombus, $ABCD$, line segments are drawn within the rhombus, parallel to diagonal $BD$, and terminated in the sides of the rhombus. A graph is drawn showing the length of a segment as a function of its distance from vertex $A$. The graph is:

$\textbf{(A)}\ \text{A straight line passing through the origin.}\\ \textbf{(B)}\ \text{A straight line cutting across the upper right quadrant.}\\ \textbf{(C)}\ \text{Two line segments forming an upright V.}\\ \textbf{(D)}\ \text{Two line segments forming an inverted V.}\\ \textbf{(E)}\ \text{None of these.}$

• Ok, look, lets call B1D1 and B2D2 - two different segments of lines, that are parallel to BD. Let dist(B2D2, A) > dist(B1D1, A). So triangles AB2D2 and AB1D1 are almost similar: AB2 = $alpha * AB1$, AD2 = $alpha * AD1$ and B2D2 = $alpha * B1D1$, and $alpha$> 1 – Cheburek Sep 14 '17 at 17:49
