Trigonometria

The Trigonometry (triangle: triangle and flowmetry: measurements) is the study of mathematics responsible for the relationship between the sides and angles of a triangle. In right triangles (have an angle of 90 °), the relations are called remarkable angles, 30 º, 45 º and 60 º, which have constant values ​​represented by sine relations, cosine and tangent. Triangles have no right angles, conditions are adapted in finding the relationship between the angles and sides.
