You can calculate the area of any triangle by using trigonometry.
One formula for the area of a triangle is:
Area = × base × perpendicular height
You can use trigonometry to adapt this formula for use when the perpendicular height of
the triangle is not known.

The area formula for any triangle ABC is: Area = ab sin C
where a, b are two sides and angle C is their INCLUDED angle
