Question

Луч BK не делит угол ABC на два угла, так как он не исходит из вершины угла ABC, но __________________________.

Answer 1

Но совпадает со стороной этого угла 

Answer 2

Answer in detail. Ray BK does not divide angle ABC into two angles, because it does not originate from the vertex of angle ABC, but _____________.

One possible way to complete the sentence is:

Ray BK does not divide angle ABC into two angles, because it does not originate from the vertex of angle ABC, but intersects the side AC at point K. This means that ray BK is not an angle bisector of angle ABC, but a segment bisector of segment AC. To divide an angle into two equal angles, a ray must pass through the vertex of the angle and split the angle into two congruent parts. For example, ray BD is an angle bisector of angle ABC, because it originates from point B and divides angle ABC into two angles of equal measure. You can see a diagram of this situation [here].
