The perm pattern also known as 9-block is called what?

• A. Rectangle pattern
• B. Triangle matrix
• C. Cross grid
• D. Diamond net

Answer: (A)

The idea being tested is recognizing the shape that a nine-block arrangement forms. A “9-block” perm pattern is described by its geometry as a rectangle pattern because the nine blocks are laid out in a rectangular grid, typically a 3 by 3 arrangement. This rectangular layout is the defining feature, which is why the label fits best. The other shapes imply different geometries: a triangle matrix would be a triangular arrangement, a cross grid would form a plus-shaped pattern, and a diamond net would create a diamond-shaped cluster. Since the nine blocks align into a rectangle, rectangle pattern is the most accurate description.
