trigonometric ratios or formulas: Part I) Model Problems. Example 1: Consider right DEF pictured at right. We know one acute angle and one side, and our goal is to determine the length of the unknown side x. Step 1: Place your finger on the 38° angle (the acute angle), and then. label the three sides: the hypotenuse. is always the longest side ...

We will complete our examination of trigonometry by learning how to use two formulas that work for all triangles, not just right ones. “Solving” a general triangle means finding out the sizes of all 3 angles and all 3 sides, when you are given three of these six facts, including the length of one side.

Triangles are classified according to their angles and sides. Angle classifications: Acute triangles have all angles less than 90(. Right triangles have one angle of 90(. Obtuse triangles have one angle greater than 90(. Side classifications: Equilateral triangles have all sides the same length. Isosceles triangles have two sides of the same ...
