Algebra is not difficult! Algebra is just different. Time is required in order for things that are different to become things that are familiar. Often we learn better, quicker, and more when we collaborate!
This is concave polygon. You can tell if its concave if you can draw a line segment with both end points inside of the polygon and part of the line goes out. If you draw a segment with one point at the top tip of the arrow and one at the bottom, it goes out twice. therefore this shape is a concave polygon.
