The point where strokes join at the top of the letters (examples: A)?

• A. Vertex
• B. Notch
• C. Apex
• D. Cap

Answer: (C)

In typography, the point where strokes meet at the top of a letter form is called the apex. Take a letter like A: the two diagonal strokes rise and converge to a sharp point at the top, which is the apex. This term is used to describe that topmost meeting point of the strokes, even when some fonts render it rounded rather than pointed.

Vertex is a general geometric term for any corner where lines meet, but typography uses apex specifically for the top meeting point of letter strokes. Notch refers to an indentation or cut in a stroke, not the meeting point. Cap describes the cap height—the distance from baseline to the top of uppercase letters—which is about height, not the point where strokes join. So apex is the precise term for the described feature.
