When hikers and skiers go into terrain with a risk of avalanches, they take safety equipment including avalanche rescue beacons. An avalanche rescue beacon sends and receives electromagnetic field signals that travel in circular patterns. The search pattern used to locate a beacon buried in the snow is based on the properties of chords and diameters in circles. This activity uses Cabri Jr. Geometry software to model an avalanche search pattern.
