im.g.1.18.1.Quilt 4-square Blocks
Instructions
Drag the blue dots to move patterns from the left into the squares at right.
Do not overlap the patterns when placing them into the squares.
You are to make four 4-block patterns as follows:
1. In the upper left square make a pattern that has ONLY 1 diagonal line of symmetry.
2. In the upper right square, make a pattern that has ONLY 1 vertical line of symmetry.
(If yours has horizontal symmetry, redo it to make it vertical.)
3. In the lower left square, make a pattern that has at least 2 lines of symmetry: along both diagonals.
4. In the lower right square, make a pattern that has at least 2 lines of symmetry: both vertically and horizontally.
