In a right triangle, the tangent of a given angle is the length of the side opposite the angle divided by the length of the side adjacent to the triangle.
In a right triangle, the ratio of the length of the side opposite an angle to the length of the side adjacent to the angle.
Tangent of Angle A = BC\AC Tan of Angle A = opposite\adjacent.
A trigonometric function of an angle which is defined as the ratio of the lengths of the leg opposite to the leg adjacent to an angle in its right triangle.
The tangent of a right angle is the ratio of the length of the opposite leg to the length of the adjacent leg.
(trig) Ratio of the opposite side to the adjacent side of a right-angled triangle
When an angle in a right angle is X, the tangent of x is the ratio of lengths of the side opposite x to the side adjacent to x.
