Question

which angle is adjacent to $\angle cda$?
(there is an image with points a, b, c, d and rays from d, and a blank to fill the angle symbol and the angle name, and a submit button)

Explanation:

Step1: Define adjacent angles

Adjacent angles share a vertex and one side, no overlapping interior.

Step2: Identify ∠CDA components

∠CDA has vertex D, sides DC and DA.

Step3: Find matching adjacent angle

∠ADB shares vertex D and side DA with ∠CDA, no overlap.

Answer:

$\angle ADB$
