Task Analysis

The task involves establishing a correspondence with the correct answers based on the given information about a line, a point K not lying on the line, and points A, B, C, D lying on the line. It is also known that KB is perpendicular to the line, KA = KC, and ∠KCD is an obtuse angle.

Solution

Based on the given information, the correspondence with the correct answers can be established as follows:

1. KB is the altitude of the triangle KAC. 2. KA = KC. 3. ∠KCD is an obtuse angle. 4. The point K lies inside the circle passing through points A, C, and D.

Let's establish the correspondence with the correct answers based on the given information.
