  1. Introduction to distance and midpoint

  2. Video Why math is important

  3. Bellringer Point R is contained in WZ. What is the probability that R is contained in YZ? Z 3 ft 1 ft Y X 2 ft W

  4. Your first TEST will be next Friday, August 31st!! • You can study sections 1.1-1.3 in your textbook

  5. Distance and Midpoints CGT.5.G.1 Objective: I will use formulas to find the distance between two points on a coordinate plane and the midpoint of a segment

  6. Distance and Midpoint on a number line

  7. Distance on a number line To find the distance between two points on a number line, take the absolute value of their difference. A B AB= ∣ -4 - 1∣ = ∣-5∣=5 AB is 5 units

  8. Midpoint on a number line To find the midpoint between two points on a number line, average the coordinates of the two points. A B The midpoint of AB is (-4+1)/2=-3/2=-1.5

  9. The Distance Formula Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:

  10. Use the distance formula to find the distance between S(-3,2) and T(6,5)

  11. The midpoint formula Given the two points (x1, y1) and (x2, y2), the midpoint between these points is given by the formula:

  12. Find the coordinates of the midpoint of a segment having the given endpoints • X(-4,3) Y(-1,5)

  13. Point M is the midpoint of AB. What is the value of x in the figure? B(2x,2x) M(7,8) A(4,6)

  14. Find the coordinates of the missing endpoint given that S is the midpoint of RT T(-4,3),S(-1,5)

  15. Find the coordinates of the missing endpoint given that S is the midpoint of RT T(2,5),S(-2,2)

  16. Triangle Activity Show all work. This will be graded!!! You will be given a set of points and a coordinate plane. Follow the directions completely for full credit.

  17. TEST Wednesday!!! PRACTICE PROBLEMS
