Answer:

B. The SAS Postulate

Step-by-step explanation:

In the given figure, we are shown two triangles,
\triangle ADE and
\triangle ABC.

Since triangle ADE is inscribed in triangle ABC, both triangles must share angle
A. Furthermore, let's take a look at the two legs of each triangle, if we say that their respective bases are DE and BC.

Compare the corresponding legs of each triangle with proportions:


(AC)/(AE)=(10)/(5)=2,\\\\(AB)/(AD)=(8)/(4)=2,\\\\\overline{AC}:\overline{AE}=\overline{AB}:\overline{AD}

Since two corresponding legs/sides of triangle are in a constant proportion, the triangles must be similar from the SAS (Side-Angle-Side) Postulate.

Step-by-step explanation:
Both triangles share angle A, and their sides can be proven similar because the ratios of 4:8 and 5:10.
