The Trigonometric Ratios

Interactive practice questions

Write down the ratio represented by $\cos\theta$cosθ.

A  right-angled triangle labeled with vertices A, B, and C is shown. The angle at vertex A is labeled $\alpha$α. The angle at vertex B is labeled $\theta$θ. The angle at vertex C is a right angle as indicated by a small square. Opposite vertex C is side AB, which is the hypotenuse. Side BC is adjacent to angle $\theta$θ. Side BC is opposite angle $\alpha$α. Side AC is adjacent to angle $\alpha$α. Side AC is opposite angle $\theta$θ.
