. Today in class, we completed the notes on circles on pages 34 - 36 in your packet. Homework: Complete the odds on pages 44 - 49 in your Unit 5: Modeling packetToday we learned: - First, you need to know the center of a circle and then you need to know the radius of a circle. If you are not given those, you have to figure it out from the information given. - When you know the center of a circle and a point on the circle, use the distance formula using these 2 points to find the radius. - When you know the endpoints of a diameter of a circle, use the midpoint formula to find the center of the circle, then... - Use the distance formula using the center (the point you just found) and one of the endpoints of the diameter (it doesn't matter which one) to find the radius - Complete the square for x and y to change the equation of a circle from general form to standard form. - Multiply the binomials with x and y to change the equation of a circle from standard form to general form. - Verify if a point is on a circle. Pictures of notes are below: Page 34 - 36 notes:

Geometry is the hardest part of my academic year. As a high school student, I do not really have huge subjects to deal with. In my opinion, I am a pretty average student in terms of what I can accomplish. I am not that bad at any subject, that is, of course, except Geometry. Mathematics is really hard for me, and Geometry is the hardest part that I had to deal with. I hope that I can understand Geometry soon.
