Publisher Summary This chapter focuses on trigonometry. The term trigonometry comes from Greek and means the measurement of triangles. A triangle is described by three angles and three sides. The chapter describes oblique triangles and discusses two general properties of triangles that are needed for the solution of oblique triangles.

Publisher Summary This chapter describes the tangent of an angle by drawing and measurement. The tangent of an angle is found by dividing the perpendicular of an angle by its base. The sine of an angle is found by dividing the perpendicular of an angle by the hypotenuse. The sine tables are used in exactly the same way as tangent tables. The cosine of

Given two points A and B, if one rotates B around A through 60° to a point B’, then the triangle ABB’ is equilateral. A consequence of this result is the following property of the equilateral triangles, which was noticed by the Romanian mathematician D. Pompeiu in 1936. Pompeiu’s theorem is a simple fact, part of classical plane geometry. Surprisingly,
