What is the rhetorical triangle and how can it be applied to visual arguments?

The rhetorical triangle was invented by Aristotle and it consists of the three ways in which someone can appeal to their audience in an argument. The three areas are called ethos, pathos and logos, and they all influence one another. Ethos is the part of the argument that appeals to the morality and credibility aspects. Pathos is the part of the argument that appeals to emotions. And, logos is the part of the argument that appeals to both logic and reason.
The rhetorical triangle can be applied to visual arguments because, even if it is a visual argument, someone is trying to appeal to their audience. In a visual argument, the visual needs to appeal to its audience in the three areas of the rhetorical triangle (ethos, pathos and logos). For example, if the visual argument is in the form of an ad in a magazine , then it can appeal to the morality/ credibility aspect by having a person that has a good reputation on the ad. A visual can emotionally appeal to its audience by having a person on an ad that is smiling. If an ad has something written on it that logically makes sense then it will appeal to the logic/reason aspect of the rhetorical triangle. All three of the areas work together to help make an argument better, and in this case, they help make an ad seem appealing. A visual argument needs all three parts in order to be the most appealing that it can be.
