2 cards from this section. Quick, good the night before a test.
State the Law of Sines.
Think about the ratios of sides to the sine of the opposite angles.
If angle A = 60° and angle B = 30°, what is the measure of angle C?
Use the triangle angle sum property.
What does the Law of Sines relate?
Think about what changes in a triangle.
In an SSA configuration, can there be more than one solution?
Consider how angles might correspond.
A triangle has sides a = 6, b = 9, and angle A = 50°. Determine the possible values for angle B, indicating whether two triangles can exist.
You might need to consider the sine function's characteristics.
Given a triangle where sides are a = 15, b = 20, and angle A = 40°, find angle B and C using the Law of Sines.
Always remember to check angle sums in triangles.
