The Tangent Ratio

Measurement – Right Angled Triangles

By the end of this lesson you will be able to identify and calculate the following:1. The Tangent Ratio

The Tangent Ratio

The tangent trigonometric ratio for any right-angled triangle is defined:

This is abbreviated to:

The Tangent Ratio

The value of this ratio for any angle can be calculated by measuring two specific side lengths of the right-angled triangle containing that angle and dividing them.
