On Friday, we started 4.3 and learnt Ambiguous cases. Ambiguous means unclear, unknown. An ambiguous case is a situation where two triangles can be drawn given the available information; the ambiguous case can occur when the given measurements are the lengths of two sides and the measure of an angle that is not contained by the two sides. (A.S.S. to remember).
We learnt that after you calculate 'h' using SOH CAH TOA you can determine how many triangles you can make. If 'h' is longer than the given side (5.5) you can only form 1 triangle. If 'h' is shorter than the length you calculated (3.5) you cannot form any triangles, and if the length of 'h' is in between what you calculated (3.5) and the given side (5.5) you can make 2 triangles.
To start solving an ambiguous case you have to:
1. Calculate the minimum length to make 1 triangle.
2. Compare minimum length to given length
This will show you the amount of triangles you will be able to make. Once you have completed this and two triangles can be made, you have to cr
eate two cases to show the two possibilities of what the triangle could look like using sine or cosine law, which we learnt in previous units.
The next person will be Brydon! :)
