of two angles and a side of a triangle, we can solve that triangle … that is we can find the other angle and the other sides. We have learned to solve right triangles in Unit 3. In this section we learn how to solve oblique triangles – triangles that do not have a right angle. First, let’s start with a generalization for this section.
SOLVING THE RIGHT TRIANGLE
Solve the Right Triangle Example: Given a right triangle with m/B = 23o10', m/C = 90o, and measure of side a = .0345, Solve the right triangle. STEPS TO FOLLOW : 1. First find the missing angle. Since all of the angles of a triangle add up to 180 degrees and you already have a 90 degree angle

angles. As standard notation, the angles of a triangle are labeled and and their opposite sides are labeled and as shown in Figure 6.1. FIGURE 6.1 To solve an oblique triangle, you need to know the measure of at least one side and any two other parts of the triangle—either two sides, two angles, or one angle and one side.

Ambiguous Triangles G iven triangular parts SSS, ASA or AAS always guarantees a single, unique triangle. Given the triangular parts SSA, however, is different and leaves the triangle unclear, or ambiguous. The “Ambiguous Case” (SSA) occurs when we are given two sides and the angle opposite one of these given sides. The triangles resulting from this condition needs to
