Figure 2 Hinged hexagons and triangles
Drag C and focus at special angles of the rhombus at C. What kind of tiling do you get when the angle of the rhombus is 90˚ ? What kind of tiling when the angle of the rhombus is 60˚ or 120˚ ? For this angle, imagine each rhombus divided into two equilateral triangles. What if the angle is 0˚ or 180˚ ?
