- ACMNA214 – Find the distance between two points located on a Cartesian plane using a range of strategies, including graphing software.
- Elaborations: Investigate graphically and algebraically, techniques for finding distance between two points using Pythagoras' theorem.
- Distance between two points
- Cartesian plane
- Coordinate geometry
About the Lesson
Students plot points on the graph, TI-nspire determines the coordinates. The formula for the distance between two points is written on the screen. Students connect the appropriate coordinates to the formula and the answer is computed by TI-nspire. In their written notes students do the same providing for both technology support and independent determination of the distance between two points.
