A proportion is a mathematical statement expressing equality of two ratios. [1] [2]: =: a and d are called extremes, b and c are called means. Proportion can be written as =, where ratios are expressed as fractions.
[1] [2] [3] Equal quotients correspond to equal ratios. A statement expressing the equality of two ratios is called a proportion. Consequently, a ratio may be considered as an ordered pair of numbers, a fraction with the first number in the numerator and the second in the denominator, or as the value denoted by this fraction.
Its two equal sides are in the golden ratio to its base. [46] The triangle formed by two sides and a diagonal of a regular pentagon is called a golden gnomon . It is an obtuse isosceles triangle with apex angle 108 ∘ {\displaystyle 108^{\circ }} and base angle 36 ∘ {\displaystyle 36^{\circ }\!} .
Two functions and () are proportional if their ratio () is a constant function. If several pairs of variables share the same direct proportionality constant, the equation expressing the equality of these ratios is called a proportion , e.g., a / b = x / y = ⋯ = k (for details see Ratio ).
All of the right-angled triangles are similar, i.e. the ratios between their corresponding sides are the same. For sin, cos and tan the unit-length radius forms the hypotenuse of the triangle that defines them. The reciprocal identities arise as ratios of sides in the triangles where this unit line is no longer the hypotenuse.
