The Law of Sines - Math is Fun
The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle:
正弦定理 - 百度百科
正弦定理（The Law of Sines）是三角学中的一个基本定理，它指出“在任意一个平面三角形中，各边和它所对角的正弦值的比相等且等于外接圆的直径”，即a/sinA = b/sinB =c/sinC = 2r=D（r为外接圆半径，D为直径）。
Law of sines - Wikipedia
The law of sines is one of two trigonometric equations commonly applied to find lengths and angles in scalene triangles, with the other being the law of cosines. The law of sines can be generalized to higher dimensions on surfaces with constant curvature.
Law of Sines - Definition, Proof, Formula, Applications and Example
Law of sines defines the ratio of sides of a triangle and their respective sine angles are equivalent to each other. The other names of the law of sines are sine law, sine rule and sine formula. The law of sine is used to find the unknown angle or the side of an oblique triangle.

Find out how the Law of Sines can be used to calculate unknown sides and angles of any oblique triangle. Discussion of different cases are included.
Law of Sines - Formula, Proof, Examples | Sine Rule - Cuemath
What is Law of Sines? The law of sines relates the ratios of side lengths of triangles to their respective opposite angles. This ratio remains equal for all three sides and opposite angles. We can therefore apply the sine rule to find the missing angle or side of any triangle using the requisite known data.
Law of Sines - Math.net
In trigonometry, the Law of Sines relates the sides and angles of triangles. Given the triangle below, where A, B, and C are the angle measures of the triangle, and a, b, and c are its sides, the Law of Sines states:
The Law of Sines - Math Open Reference
The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.

2022年11月17日 · The Law of Sines states that the sides of a triangle are proportional to the sines of their opposite angles.
4.1: The Law of Sines - Mathematics LibreTexts
To find the lengths of the unknown sides, we'll use the Law of sines. We should start by choosing a side-angle pair for which we know both the side and the angle. In this case, we know that \(\angle C=95^{\circ}\) and side \(c=5\)
