1 Algebra II Chapter 10 Section 3

2 Circle The set of all points a given distance from some center point

3 Standard Form

4 Find the center and radius given an Equation 25 = (x – 7) 2 + (x + 4) 2 64 = (x – 3) 2 + (x - 6) 2 22 = (x + 7) 2 + (x + 11) 2 -3 = (x – 4) 2 + (x + 5) 2

5 Transformations on a circle Translation Rotation Reflection Dilation

6 Given the Equation and Translation of the following circles give the equation of the image circle x 2 + y 2 = 25 Up 2 units x 2 + y 2 = 25 Left 4 units x 2 + y 2 = 25 Down 3 and right 5 units

7 Write the equation of the circle that passes through the given point and has a center at the origin ( 9, 12) (12, -5) (2, -3)
