What is the notation for a simple state in a state machine diagram?

• A. Round-Angle
• B. Square
• C. Circle
• D. Diamond

Answer: (A)

In a state machine diagram, a simple state is typically shown as a rectangle with rounded corners. This rounded-rectangle shape communicates a stable mode or condition the system can be in, and it’s the standard symbol used in many notations (like UML) for a basic state. The other shapes are used for different purposes: a plain circle is often associated with initial or final points in many diagrams, a diamond indicates a branching decision, and a square isn’t the conventional symbol for a state. So the rounded-corner rectangle is the best match for a simple state.
