Why would you want to hyperlink objects into your own Google Slides presentation? (Select all that apply.) Select All Correct Re
asambeis [7]

The correct answers are A.  For extending the learning experience for students. C. So students can use the Slides for review and can go to additional resources outside of the presentation. D. To make the presentation more graphically appealing

Explanation:

The use of hyperlink objects in presentations means objects such as images, texts, or icons are associated with links or websites students can easily access by clicking on the specific image or element. This might be used in educational contexts to allow students to have a complete learning experience by providing alternative and external sources outside the presentation. For example, if the topic is space hyperlinks to NASA website can be included. This means, hyperlink objects extend learning experiences and provide additional resources (Option A and D).

Besides this, this resource can make a presentation more appealing as links to images, videos, and other visually interesting resources can be included (Option D). However, it also breaks the linearity of the presentation as students will need to move to other websites as they go through the presentation.
