A semi-circle is a 180 degree half circle. A semi-circle does not have any corners. A circle does not have corners either. There are points of beginning and end in a semi-circle. In a circle the point of beginning is the same as the ending point.
If, by square corners, you mean corners that are right angles, then any polygon with four or more sides can have two square corners. Furthermore, apart from near the corners, the lines need even be straight so the shape need not be a polygon. In the limit a semicircle has two right angles.
