ΔXYZ ∼ ΔGST and XY : GS = 2 : 3, XV is the median to the side YZ, and GD is the median to the side ST. The value of $(\frac{YV}{SD})^2$ is ______. |
$\frac{4}{9}$ $\frac{3}{5}$ $\frac{1}{4}$ $\frac{2}{3}$ |
$\frac{4}{9}$ |
Given ⇒ ΔXYZ ∼ ΔGST and XY : GS = 2 : 3 ⇒ \(\frac{XY}{GS}\) = \(\frac{XZ}{GT}\) = \(\frac{YV}{SD}\) = \(\frac{VZ}{DT}\) ⇒ \(\frac{XY}{GS}\) = \(\frac{YV}{SD}\) ⇒ \(\frac{2}{3}\) = (\(\frac{YV}{SD}\))2 ⇒ (\(\frac{YV}{SD}\))2 = \(\frac{4}{9}\) |
