Which term refers to the tangent on the left side of a vertex?

• A. Incoming tangent
• B. Outgoing tangent
• C. Vector Handles
• D. Bezier

Answer: (A)

In animation curves and Bezier interpolation, each keyframe has two tangents that control how the curve moves into and out of that point. The tangent on the left side of the vertex describes the slope as you approach the vertex from the previous segment, so it is the incoming tangent. The tangent on the right side describes the slope as you leave toward the next segment, i.e., the outgoing tangent. Bezier refers to the curve type and uses handles to shape tangents, while vector handles are simply the visual controls for those tangents. So the left-side tangent is the incoming tangent.
