Published on 10/19/2012

#### Activity Overview

Students plot points on a map of Australia drawn on the Cartesian plane. The coordinates of the points are used to determine the distance between successive points and the progressive distance (perimeter) of Australia.

#### Objectives

National Curriculum:
(ACMNA214) Find the distance between two points located on a Cartesian plane using a range of strategies, including graphing software.
Elaborations:
Investigating graphical and algebraically, techniques for finding distance between two points and using Pythagoras' theorem to calculate distance between two points.

#### Vocabulary

Pythagoras, distance between two points, Cartesian plane, coordinate geometry
