Exploring the Law of Sines: AAS & SSA Solutions

What is the relationship between the sides and angles in the Law of Sines?

• Side a - sin(A) = Side b - sin(B) = Side c - sin(C)

• Side a + sin(A) = Side b + sin(B) = Side c + sin(C)

• Side a * sin(A) = Side b * sin(B) = Side c * sin(C)

• Side a / sin(A) = Side b / sin(B) = Side c / sin(C)

How do you find the side opposite the largest angle in a triangle?

• It will be the longest side

• It will be the shortest side

• It is found by adding the other two sides

• It is found by subtracting the smallest side from the sum of the other two sides

What indicates a triangle has no solution in SSA scenarios?

• When the sine of an angle is greater than 1

• When a side is longer than the sum of the other two sides

• When the sine of an angle is less than 0

• When the sum of angles is less than 180
