Consider the edge-to-edge tiling from Figure 2.11(a). Slide alternating diagonal rows of triangles so that the vertex of each triangle is in the middle of a side of another triangle as shown.

a. Is the result of sliding the diagonal rows an edgeto-edge tiling?

b. Is this tiling different from the one in Figure 2.11(b)? Explain your answer. (Hint: Slowly rotate and observe the tiling for a full 360°. What do you notice?)
