The angle and focus of the discussion lies in their different steps and methods. Argumentation angle: It is the same as choosing a starting point to discuss which point or height in an argumentative essay. Choosing a good angle to enter the argument is related to the success or failure of an argumentative essay, and it is the first step to see whether the argumentative essay is well done. Discussion focus: it is an important issue or direction that the selected author thinks must be discussed first after an argumentative paper decides from what angle to discuss.
