Which type provides handles, but forces the segments into a tangent through the vertex?

Which type provides handles, but forces the segments into a tangent through the vertex?

• A. Corner
• B. Smooth
• C. Bezier
• D. Bezier Corner

Answer: (C)

In splines, how adjacent segments join is defined by the vertex type, and handles are what you use to shape the curve. Bezier vertices give you two handles—one on each side of the vertex—that control the tangents of the incoming and outgoing segments. By adjusting these handles, you set a specific tangent direction at the vertex, so the segments meet with a continuous tangent rather than a sharp corner. This is why Bezier is the right choice when you need both manipulable handles and a tangent through the vertex. Corner vertices have no handles, producing sharp corners. Smooth vertices enforce a smooth join automatically but don’t expose handles for manual tangents. Bezier Corner also provides handles but allows varying tangents that can still create a corner-like joint, so it doesn’t inherently enforce a single tangent through the vertex.
