One of the possible ways to do that is to create certain paths by using the Pen Tool (P). To do that we need to divide the shape we have just created into 5 parts. In this step, we will try to create specific ribbons that will constitute our logo. You should end up with something like this. It will cut out the middle part of the Polygon. Select both shapes and under the Pathfinder Panel hit the Minus Front button. Now we need to create a “hole” in our Polygon. Select them and under the Align Panel hit both, Horizontal and Vertical Align Center. Set the parameters as shown in the picture below and hit the OK button. Grab it from the Tools Panel and click on the Artboard to bring up the Polygon Options Box. Next thing we have to do is to create the “hole” in our modified pentagon.For that, we will use the Polygon Tool again. It will turn the object into an editable shape. Select the yellow shape and under Effect select Stylize > Round Corners. Set the Radius to 150 pixels and Sides to 5 and hit the OK button. Select it in the Tools Panel and click on the Artboard.

Make sure to set the dimensions to 500 x 500 pixels and the Color Mode to RGB.
