REAL LIFE REAL WORLD Activity - Surveyor

Activity Overview

Surveyors describe land parcels with distance and angle measurements, often given as compass headings. Once the boundaries of the land parcel are described, the surveyor can calculate the area of the land. This activity uses Cabri Jr. Geometry software to create a diagram for a sample parcel of land and find its area.
