The Area of a Triangle Using Sine
Here is a power point that introduces this topic and includes some examples. The two attached word documents are two versions of a match up type activity. The students have to then put the cards in order showing how the formula for the area of a triangle using sine has been developed. The harder version includes gaps that the students need to fill in. The final card refers to a problem that the class could be given at the start of the lesson, hence explaining the need for an additional formula.
