  27. Monday, Feb 10 Chapter 9.5 Polygons on the Coordinate Plane

  28. Polygons on the Coordinate Plane Objective: To draw polygons on the coordinate plane and use coordinates to find lengths.

  29. Polygons on the Coordinate Plane At the end of this lesson you should be able to answer the following question. How can coordinates help you find the areas of figures on the coordinate plane?

  30. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. A(-3,-4), B(-3,5), C(2,5), D(2,-4) Do this on your own.

  31. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. A(-3,-4), B(-3,5), C(2,5), D(2,-4) A = 5 x 9 = 45u²

  32. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. R(3,-2), S(7,-2), T(8,-6), V(1,-6) Do this on your own.

  33. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. R(3,-2), S(7,-2), T(8,-6), V(1,-6) A = A = A = 22u²

  34. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. X(-7,2), Y(-7,6), Z(-4,2) Do this on your own.

  35. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. X(-7,2), Y(-7,6), Z(-4,2) A = A = 6u²

  36. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. A(3,3), B(3,6), C(5,6), D(8,3) Do this on your own.

  37. Polygons on the Coordinate Plane Graph the figure then classify it (tell what shape it is). Then find the area. A(3,3), B(3,6), C(5,6), D(8,3) Area = = = = 10.5u² It is a trapezoid.

  38. Polygons on the Coordinate Plane We can also use the coordinates of a shape to find the dimensions by finding the distance between two points.

  39. Polygons on the Coordinate Plane What is the length of LK; L (1,4) K(1, 9)? To find the distance between two ordered pairs, subtract the unique numbers and take the absolute value. I4 – 9I I-5I = 5

  40. Polygons on the Coordinate Plane What is the length of ST; S (1,5) T(9, 5)? Do this on your own.
