angle abc and angle dbe are equal.

Answer 3

You can write this in the first set of blanks:

<BDE = <BAC (since, corresponding angles in a pair of parallel lines are equal)

For the second one,\[\Delta BDE\text{~} \Delta BAC\]

So, as a result of the two triangles being similar, the sides are proportional.
