polygons that have reflection symmetry. A pentagon such that one side lies flat on the bottom and the side joining the left side of this base extends straight up, while the side joining the right side of this base extends to the right at an angle. Two other segments join the ends of each these segments at a point above the midpoint of the base. A polygon is shaped like a letter T, where the top of the T is wider than its stem and the T has been rotated 90 degrees counterclockwise. A polygon is shaped like the letter L but the horizontal part is wider than the vertical part. A rhombus is oriented such that two obtuse angles are at the top and bottom of the figure and two acute angles are at the left and right of the figure.
