Problem 127 of 7
Prove a diameter creates a right angle on the circle for diameter endpoints D(-3,-3), E(3,3), point F(-3,3).
Using a hint is okay. It just tells the trainer to give you a little more review.

Point must lie on the circle with the given diameter for the theorem to apply.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Verify the point is on the circle if needed.
2. Compute slopes from the point to diameter endpoints.
3. Show the slopes are perpendicular.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Applying theorem to a point not on the circle.
