Ancient Britons may have been able to find their way by using a sophisticated geometric shapes carved out of way stones and stone circles. These prehistoric people were able to use this historic sat nav to travel hundreds of miles with remarkable accuracy using these landmarks. Researchers have investigated and found accross southern britiain prehistoric monuments are connected by a grid of isoseles triangles whose with two sides of equal length, each pointing to the next. It is believed there were ancient maths wizards who have been creditiedwith the developing geometry. Pictured is the interconnecting triangles through abbeys, churches and ancient sites which indicate it could only be a work of intelligent surveyors and planners which throw into question the origin of mathematics. It has been shown the medieval system is acurate to within 100m over distances up to 400km
