how to find area of a triangle if we are given two equal sides and angle between them
Answer provided by our tutors
If we know two sides and the included angle (SAS), there is another formula (in fact three equivalent formulas) we can use.
Depending on which sides and angles we know, the formula can be written in three ways:
Either Area = ½ab sin C
Or Area = ½bc sin A
Or Area = ½ac sin B
