**Plant Mathematics – Right Angle Trigonometry**

Solving for unknowns in right triangles using the rules of trigonometry: recognition that a triangle has three sides and three angles; that a right angle contains 90°; that a right triangle must have one right angle; that the square of the hypotenuse equals the sum of the squares of the other two sides; and that the sum of the angles is 180°. Also covered are: the definition of the side opposite and the side adjacent to an angle; definition and use of sine, cosine, and tangent functions; and how to handle any triangle using rules of right angle trigonometry.

Prerequisites: *A knowledge of basic mathematics and the ability to use tables of squares and square roots.*
