The term "metafacial angle" refers to the angle between the forehead and the nose on one's face. Although this specific term may not have many synonyms, there are alternative ways to describe this facial feature. For instance, the "forehead-to-nose angle" could be used to convey the same meaning. Additionally, one might refer to it as the "facial slope", "forehead-to-bridge angle", or even the "frontonasal angle". While these synonyms may not be commonly used in everyday conversation, they can still serve as effective substitutes when describing the angle formed between the forehead and the nose on a person's face.
