Which of the following facial shapes resembles an upside-down triangle?

The facial shape that resembles an upside-down triangle is the inverted triangular, or heart shape. This shape is characterized by a wider forehead that tapers down to a narrower chin, resembling an upside-down triangle. Individuals with this shape often have prominent cheekbones and a pointed chin, which further accentuates the triangular silhouette.

Understanding facial shapes is essential in cosmetology and beauty practices, as it helps in determining the most flattering hairstyles, makeup application techniques, and even eyewear choices for enhancing one’s features. The inverted triangular shape specifically calls for styles that provide balance and softness to the jawline and forehead, highlighting the cheeks without drawing attention away from the person's natural features.
