  1. Use Midpoint and Distance Formula Lesson 1-3

  2. Warm Up • Find a point between A(-3,5) and B(7,5). • Find the average of -11 and 5. • Solve • Find 30 to the nearest hundredth. • Find 5 +20 to the nearest hundredth.

  3. Midpoint Definition: A point that divides a segment into two congruent segments

  4. G H I J K L N O P Q R S -5 5 Midpoint on Number Line - Example Find the coordinate of the midpoint of the segment PK. M 0 Now find the midpoint on the number line.

  5. Segment Bisector Definition: Any segment, line or plane that divides a segment into two congruent parts is called segment bisector.

  6. Identify the segment bisector of PQ . Then find PQ. 1. ANSWER MN; 3 3 4 Practice

  7. Identify the segment bisector of PQ . Then find PQ. 2. 5 ANSWER line l ; 11 7 Practice

  9. Midpoint Formula The coordinates of the midpoint of a segment are the averages of the x-coordinates and of the y coordinates of the endpoints. If A(x1,y1) and B(x2,y2) are points in a coordinate plane, then the midpoint M of AB has coordinates

  10. The endpoints of ABare A(1, 2) andB(7, 8). Find the coordinates of the midpoint M. ANSWER (4,5) The midpoint of VWis M(– 1, – 2). One endpoint is W(4, 4). Find the coordinates of endpoint V. ANSWER (– 6, – 8) Practice

  11. Distance Formula If A(x1,y1) and B(x2,y2) are points in a coordinate plane, then the distance between A and B is
