Go to the Illustrator toolbox and select the line segment tool and draw the line (you can use the other tools to draw lines as well) and then if you wish to use the line as 'proper shape' or closed path in Illustrator then you can expand the line using the Object menu expand command. Best bet, add a decent stroke width or perhaps use width profiles with the line to get more interesting shape. You can also use width tool to drag out the 'width' of the stroke - this can also then be converted into a closed path (shape). If you mean shape as a 'Illustrator symbol' - simply drag the line over to the symbols palette to save it as Illustrator shape for future use.
If divided by a vertex-to-vertex line, it is an isosceles trapezium. If divided by a line from one side to the opposite side, it will make an irregular pentagon.

Bezier handles are the dumbbell like lines that are connected to the anchor points of a line. They are used to make curves in a line.
If you mean trace as in the option in Illustrator you cannot. The easiest way and pretty much the only way is to use the pen tool. You add nodes to each curve and line around the object you're tracing then when completed it will close the shape. If you plan on using this shape in illustrator go to File/Export Paths to Illustrator. Then it will give you the option to save it as an AI or EPS. If you'd like to continue using photoshop for this shape, then double click on the gray screen or File/Open then open your vector file.
