Final answer:
To make pattern block rhombuses using 8 triangles, we divide the number of triangles by the amount of triangles needed to make a rhombus.
Step-by-step explanation:
The pattern block rhombus is made up of 8 triangles. To find how many pattern block rhombuses can be made using 8 triangles, we need to divide the number of triangles by the amount of triangles needed to make a rhombus.
Since each pattern block rhombus requires 2 triangles, we divide 8 by 2:
8 triangles ÷ 2 triangles/rhombus = 4 rhombuses
Therefore, 8 triangles can be used to make 4 pattern block rhombuses.
