Final answer:
To determine how many pattern block rhombuses make a triangle, one must consider the geometry of the shapes and how they fit together. Typically, two rhombuses make up one of the smaller triangles in a pattern block set, but without specific measurements, it's not possible to definitively answer for the larger triangle in the given options of 3, 4, 6, or 9 rhombuses.
Step-by-step explanation:
To determine how many pattern block rhombuses make a triangle, we need to consider the geometric shapes and how they can fit together. A pattern block rhombus, often used in mathematical activities, is a type of rhombus that can fit together with other shapes to form larger patterns. When combining pattern block rhombuses to make different shapes, it's essential to look at the angles and sides of the rhombuses to see how they can be arranged to create a new shape such as a triangle.
In the case of a typical pattern block set, it takes two rhombuses to make up one of the smaller triangles in the set. However, the question might be referring to a specific type of triangle. If we are considering a larger triangle composed of smaller rhombus-shaped pattern blocks, we would arrange the rhombuses in a way that the acute angles (smaller angles) of the rhombuses meet at a point, forming a triangle shape. Without the specific measurements of the rhombuses and the triangle in question, we cannot definitively say how many rhombuses would form that triangle. Answer options provided such as 3, 4, 6, or 9 rhombuses per triangle would depend on the size of both the rhombuses and the triangle they are forming.
