PSI Texas State Board Nail Tech Practice Exam

The correct answer is based on the classification of nail shapes. Basic nail shapes typically include common styles that are widely recognized and practiced in nail technology. Square, round, and stiletto shapes represent the standard forms that nail technicians often use and are familiar with. Square nails have straight edges and a squared-off tip, round nails have gentle curves that mimic the shape of a natural fingertip, and stiletto nails are characterized by a long, tapered point that creates a dramatic look.

On the other hand, the cone shape does not conform to these established categories. It is not recognized as a standard nail shape in nail technology. Therefore, it falls outside the commonly accepted definitions of basic nail shapes, affirming why this option is the correct choice in identifying which is not considered a basic nail shape. Understanding these standard shapes is crucial for nail technicians when servicing clients and meeting their desired aesthetic preferences.
