Problem 116 of 7
Use coordinates to prove chord relationship chords y=0 and y=4 in circle (x-1)^2+(y-2)^2=10 are equidistant from center.
Using a hint is okay. It just tells the trainer to give you a little more review.

use distance and midpoint relationships.
Hidden until you reveal it.
Proof must use distance, midpoint, or center-to-chord distance relationships.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify endpoints, midpoint, or chord line distance.
2. Compute the coordinate measure needed.
3. Connect equal measure to the chord theorem.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using unrelated endpoint coordinates without circle-center evidence.
