  1. Chapter 6: Quadrilaterals 6.6 Placing Figures in the Coordinate Plane

  2. Review • Distance Formula: • Slope Formula: • Midpoint Formula:

  3. Review • Determine the most precise name of a quadrilateral with vertices H(-5,0), E(-3,2), A(3,2), and T(5,0).

  4. Placing Figures • in the coordinate plane, if we are not given specific coordinates, we can place one vertex at the origin, to make it easier • we can also change the scale of the graph, to avoid fractions

  5. Example 1 Is the inner quadrilateral a parallelogram? Explain.

  6. Example 2 • Rectangle KLMN is centered at the origin with sides parallel to the axes. Find the missing coordinates.

  7. Example 3 • Give coordinates for points D and S without using any new variables.

  8. Example 4 • Give coordinates for points D and S without using any new variables.

  9. Example 5 • Find coordinates for points D and S without using any new variables.

  10. Example 6 • Give coordinates for points D and S without using any new variables.

  11. Homework • p. 344: • 2-7, 23-25
