What are the basic angles in degrees you should know in standard form

The video tutorial reviews basic angle concepts, starting with 30 degrees on an XY axis. It covers essential angles such as 90 degrees, 180 degrees, and explains how these angles add up to form a full circle of 360 degrees. The tutorial emphasizes the importance of understanding these angles for sketching and other applications.
