# What is the tangent side of a triangle?

## What is the tangent side of a triangle?

In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as ‘tan’.

What is SEC the opposite of?

The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

What is the longest side of a right triangle?

hypotenuse
We define the side of the triangle opposite from the right angle to be the hypotenuse, h. It is the longest side of the three sides of the right triangle. The word “hypotenuse” comes from two Greek words meaning “to stretch”, since this is the longest side.

### What is a tangent in conversation?

A tangent is an entirely different topic or direction. The non-mathematical meaning of tangent comes from this sense of barely touching something: when a conversation heads off on a tangent, it’s hard to see how or why it came up.

What is sec theta equal to?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).

What is the tangent of a right triangle?

The tangent of a given angle in a right triangle is the ratio of the length of the opposite side to the length of the adjacent side. The tangent function is defined by the formula:

#### How to use the tangent function to find the adjacent?

Using the Tangent Function to Find the Adjacent. Using the Tangent Function to Find the Adjacent of a Right Triangle. The tangent function relates a given angle to the opposite side and adjacent side of a right triangle.

How many adjacent sides are there in a triangle?

every triangle will have 3 pairs of adjacent sides (each side will be an ‘adjacent’ side to 2 of the angles. each side of the triangle will be an opposite side to the angle that it doesn’t form a vertex with.

How is the tangent of an angle calculated?

Tangent (tan) function – Trigonometry. In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Try this Drag any vertex of the triangle and see how the tangent of A and C are calculated.
