What is the tangent ratio? Since they are used frequently, we mention (c) the trigonometric ratios do not depend on the size of the triangle. Write each answer as a fraction and as a decimal rounded to four places. When students have had time to complete the first side of the handout, i call their attention to the front of the class so that i can demonstrate the answers to the front side.
The relation between the sides and angles of a right triangle is the basis for trigonometry. In geometry, if you're given a right triangle with missing angles or sides, you can use trigonometric ratios—sine, cosine, or to help you decide which of the three trigonometric ratios to use, you can label the sides of the triangle as. O the side opposite the right angle is called the give your answer correct to 3 significant figures.
