In mathematics, the law of cosines, also known as the cosine rule or the cosine formula, is a formula used to calculate the cosine of an angle in a triangle, given the lengths of the sides of the triangle and the angle itself. It is one of the basic facts in Euclidean geometry.

In geometry, the area of a triangle is the number of square units that compose the triangle. It is the base times the height of a triangle: A = b h where "b" is the length of the base (or "base") and "h" is the height (or "altitude"). The area can also be calculated using the Heron's formula: A = 1/2 bh where "b" is the length of the base and "h" is the height. This formula only works for right triangles. The area is also equal to the average of the lengths of the bases times the height: A=b h = 1/ 2 ( b + h ).

In mathematics, the law of cosines, also known as the cosine rule or the cosine formula, is a formula used to relate the sides of a triangle (or a polygon with three or more vertices) in Euclidean plane geometry. The law of cosines was known to ancient Indian and Babylonian mathematicians. The law of cosines was also known to ancient Chinese mathematicians, but the name of the law of cosines was given by European mathematicians.

In trigonometry, the law of sines is a formula used to relate the sides of any triangle to the sines of its angles. The law of sines may be derived from vector addition of the angles and sides of a triangle.

In mathematics, the area of a triangle is half the base times the height. It is a generalization of the concept of area in Euclidean geometry, where the base and height are the sides of the triangle and where the area is the length of any side times the area of the triangle.

In trigonometry, the law of sines, also called the law of sines, is a trigonometric identity relating the sides of a triangle to the lengths of its three angles. The law of sines is a special case of the law of cosines, since cos(A) = sin(A) / sin(A).
