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:

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 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.

What is the law of sines? The Law of Sines (or the sine rule) is a proportional relationship between the size of an angle in a triangle and its opposite side. The Law of Sines is used to find the missing sides and missing angles of a triangle.

The law of sines in Trigonometry can be given as, a/sinA = b/sinB = c/sinC, where, a, b, c are the lengths of the sides of the triangle and A, B, and C are their respective opposite angles of the triangle.

The Law of Sines is also known as the sine rule, sine law, or sine formula. It is valid for all types of triangles: right, acute or obtuse triangles. The Law of Sines can be used to compute the remaining sides of a triangle when two angles and a side are known (AAS or ASA) or when we are given two sides and a non-enclosed angle (SSA).

2024年8月5日 · Law of sine is the ratio of the side length to the sine of the opposite angles. For a triangle with sides, a, b, and c with respective angles, ∠A, ∠B, and ∠C the sine law states that, a/sin A = b/sin B = c/sin C. The law of sine formula is used to find the relation between the lengths of a triangle’s sides to the sines of consecutive angles.
