  1. Bellringer Find the circumference and area of the circle. 4/3 cm

  2. Edmodo Geometry Group Code: ct0qec

  3. Chapter 2.1 Segment bisectors

  4. Midpoint • The midpoint of a segment is a point halfway between the endpoints of a segment. If X is the midpoint of AB, then AX=XB A X B

  5. Segment bisector • A segment bisector is a segment, ray , line, or plane that intersects a segment at its midpoint. • To bisect a segment means to divide the segment into two congruent segments. A C B

  6. Midpoint and Distance • Midpoint formula Midpoint = • Distance formula d = (x2 – x1)2 + (y2 – y1)2 x1 + x2 , y1 + y2 2 2

  7. Example of midpoint • Find the midpoint of X(4, 2) and Y(2,0)

  8. Example of distance • Find the distance between X(4,4) and Y(0,1)

  9. Classwork/Homework • Pg. 56 #2-34 even • Edmodo • Group Code: ct0qec
