Intro to Trigonometry Goals: To use the sine, cosine, and tangent to solve problems involving right triangles. Essential Understandings: In a right triangle, the ratios of the lengths of the sides; hypotenuse, opposite leg, and adjacent leg, depends on the angle measures. If the right triangles are similar, these ratios will be equal. You can completely solve a right triangle knowing only the length of two sides, or one side and one acute angle.
