... Question: Can a triangle have two obtuse angles? Why or Why not? When describing triangles, we can refer to the sides and angles as "opposite" each other. For example, we might say, "The side opposite the right angle is the longest side of the right triangle." The side opposite an ̅̅̅̅ is the side o ...

Rule of marteloio

The rule of marteloio is a medieval technique of navigational computation that uses compass direction, distance and a simple trigonometric table known as the toleta de marteloio. The rule told mariners how to plot the traverse between two different navigation courses by means of resolving triangles with the help of the Toleta and basic arithmetic.Those uncomfortable with manipulating numbers could resort to the visual tondo e quadro (circle-and-square) and achieve their answer with dividers. The rule of marteloio was commonly used by Mediterranean navigators during the 14th and 15th centuries, before the development of astronomical navigation.
