In parallelogram ABCD point K belongs to diagonal
Maksim231197 [3]

Answer:

\dfrac{BE}{EC}=\dfrac{1}{3}.

Step-by-step explanation:

Consider triangles BKE and DKA. In this triangles:

  • \angle BKE=\angle DKA as vertical angles;
  • \angle KBE=\angle KDA as alternate interior angles (lines BC and AD are parallel and BC is a transversal);
  • \angle BEK=\angle DAK as alternate interior angles (lines BC and AD are parallel and BE is a transversal).

Thus triangles BKE and DKA are similar by AA theorem. Similar triangles have proportional sides lengths:

\dfrac{BK}{KD}=\dfrac{BE}{AD}\Rightarrow \dfrac{1}{4}=\dfrac{BE}{AD}.

Thus, AD=4BE.

Since AD=BC and BC=BE+CE, we have that 4BE=BE+EC, EC=3BE. Hence, the ratio BE to EC is

\dfrac{BE}{EC}=\dfrac{BE}{3BE}=\dfrac{1}{3}.
