Which statements describe guidelines for the use of graphics in presentations? their use will make a bad presentation good. there should be at least one graphic element on each slide. they should be appropriate and relevant to the presentation's content. they should be large enough to be seen by your audience. they should only be used when they enhance the content of the presentation.

I will discuss each of them in turn:

Their use will make a bad presentation good.
-no, this is false: just inserting graphics will not save a bad presentation.

There should be at least one graphic element on each slide.
-this is also false: the decision whether there should be a graphic depends on the content of the presentation!!!

They should be appropriate and relevant to the presentation's content.
-yes, this is true and probably the most important rule!

They should be large enough to be seen by your audience.
-this is correct! if they can't be seen then they're only confusing the audience!!!

They should only be used when they enhance the content of the presentation.  -this is also true!
