What is the area formula of an obtuse triangle?
Determine the area formula of an obtuse triangle.
An obtuse triangle is a triangle whose one angle is obtuse that is greater than .
Consider a triangle where is an obtuse angle
As it can be seen, the Area of is equals a difference between the area of .
Since,
Now
Area of
And
Area of
Calculate the difference of the above equation:
Where is the base of the and is the height perpendicular to extended
Hence, the area formula of an obtuse triangle is “”.
