These math worksheets should be practiced regularly and are free to download in PDF formats. We will calculate trigonometric ratios for some specific angles and establish some identities involving these ratios, called trigonometric identities. Trig Cheat Sheet Definition of the Trig Functions Right triangle definition For this definition we assume that 0<<or 0 °< < 90°. We will also define the trigonometric ratios for angles of measure 0° and 90°. Download Trigonometric Ratios Worksheet PDFs However, these ratios can be extended to other angles also. Real-life examples of trigonometric ratio include areas such as astronomy, geodesy, surveying, and navigation. By solving Trigonometric ratios worksheets, you'll understand that the trigonometric ratios are given by the trigonometric functions of the known angle A, where a, b, and c are lengths of the sides of the figure produced. Trigonometry is widely used in day-to-day applications.
