You can use a circle to describe a safety zone for fireworks, a location on Earth seen from space, and even a rainbow. You will learn about angles of a circle when satellites send signals to Earth in Lesson 10-6. Chapter 10Circles521

Hint: In this problem, we are not given the center or radius however we can find the length of the diameter using the distance formula (Phythagoras) and then divide it by 2. The center is simply the midpoint of the given points.

If the endpoints of an arc lie on a diameter, the arc is a .... Q. A ____ angle is an angle whose vertex is a the center of a circle. Q. Find x. Assume that segments that appear to be tangent are tangent. Q. QS is a tangent to circle P. Solve for PR. Q. Find x. Assume that segments that appear to be tangent are tangent.
