The relation between the sides and angles of a right triangle is the basis for trigonometry.
Measuring contact angles with a high level of precision usually requires high-tech contact angle goniometers that can perform a great number of automated measurements (N = 50-100) per drop, thus, reducing the error on each returned average value (10).
000.1 - The Law of Cosines and Sines c 2010 Treasure Trove of Mathematics The law of cosines and the law of sines are two trigonometric equations commonly applied to find lengths and angles in a general triangle.1 1 The Law of Cosines Suppose we have a triangle labeled by the vertex points A, B, and C, sides a, b and c, and angles α, β, and γ, as shown in Figure 1.
