Drag the blue dots to move patterns from the left into the squares at right.[br]Do not overlap the patterns when placing them into the squares.[br][br]You are to make four 4-block patterns as follows:[br][br]1. In the upper left square make a pattern that has ONLY 1 diagonal line of symmetry.[br][br]2. In the upper right square, make a pattern that has ONLY 1 vertical line of symmetry. [br](If yours has horizontal symmetry, redo it to make it [i]vertical[/i].)[br][br]3. In the lower left square, make a pattern that has at least 2 lines of symmetry: along both diagonals.[br][br]4. In the lower right square, make a pattern that has at least 2 lines of symmetry: both vertically and horizontally.
