Textbook has frequent boxes that include a title > subtitle, which are separated by a graphic mark, resembling an arrowhead or closing angle bracket. I also notice that this mark, and the subtitle are in bold. So, after you view the image, please correct me if I’m wrong here. I used a bold closing angle bracket because that’s what it resembles, but it looks like some kind of an arrowhead to me, and I am having problems locating the proper symbol to use. Thanks!
