Notice it always remains an equiangular triangle. The angles A,B and C always remain equal in measure. An equiangular triangle is a triangle where all three interior angles are equal in measure. Because the interior angles of any triangle always add up to 180Â°, each angle is always a third of that, or 60Â° The sides of an equiangular triangle are all the same length (congruent), and so an equiangular triangle is really the same thing as an equilateral triangle. See Equilateral Triangles. Properties
Using a sextant, measure the angle between the horizon and the North Star. The angle of inclination on the sextant eyepiece will give you the Latitude that you are standing/sailing at. latitude is measured east and west of the Equator.
