1. What is the equation of the circle with the given graph?

Look at the picture. What is the center point? How must this be represented in the circle equation? Which two answer-options can you then cross off the list?

Look again at the picture. What is the value of the radius? How must this be represented in the circle equation? Which other answer-option can you then cross off the list?

So what is the answer?

4. In the circle O, which of the following is a chord?

What is the definition of a "chord" of a circle? Which segment fulfills that definition? So which segment is the chord?

Which of the angle-values below is \(\displaystyle \, m\angle (FAD)\)?

You are given that FD is of the same length as DE. You know that |AD| = |AD|. You know that all the radii of any given circle must have the same length. What does this tell you about the two triangles AFD and AED? Then what do you know about the angles FDA and EDA? Then what must be the measure of angle FAD?

Please be complete. Thank you!
