News writing has to do with when people write for publication which can be in a magazine, newspaper, etc. A topic simply means the subject that a writer or s person is discussing or writing on. The topic helps in having an idea on what the paragraph will be about.
The angle of a particular story or new simply means the point of the story. Angle is the viewpoint through which writers typically share their stories.
It should be noted that the topic is bigger as it is more detailed than the angle.
