The sine rule for the triangle is given by, = = Note: The sine rule is used to solve triangles when it is given: two sides and a non-included angle, or, two angles and one side. The Sine Rule : Ambiguous case. The ambiguous case occurs when 2 sides and 1 angle of a triangle are given with the angle opposite the shorter side.

Apply the Sine Rule and the Cosine Rule to solving Triangles. Sine Rule. In any abc: a b c. sin A sin B sin C. In words: The sines of the angles of a triangle are in the same ratio to the lengths of the opposite sides. This is known as the sine rule, and it applies to any triangle, including a right-angled triangle.

Triangles without a right angle. Sine rule: Use this formula to find a side length: Use this formula to find an angle: Cosine rule: Use this formula to find a side length: Use this formula to find an angle: Use the cosine rule if you know all 3 sides (to find an angle) OR. if you know 2 sides and the angle in between (to find the 3rd side).

Derive a formula for the area of any triangle given two sides and the angle between them. Derive the Sine Rule. Practice finding the area of non-right triangles. Practice using the Sine Rule to find unknown angles and sides of non-right triangles. This is how the sides and angles of a non-right triangle are labelled conventionally:

In trigonometry, the ambiguous case refers to using the sine rule to calculate the size of an angle in a triangle where there are two possibilities for the angle, one obtuse and one acute, leading to two possible triangles. ... Students may investigate by constructing a right-angled triangle (for example – the Pythagorean triangle with sides ...

When using the sine rule to find an obtuse angle, students should apply the sine rule as usual and interpret the result using sin (180°-A) = sin A , which means subtracting the resulting angle from 180° to determine the obtuse angle.
