#0, Triangle's area rate of change Posted by JE on Jul-23-07 at 09:38 AM I'm trying to find a relation between the area of an scalene triangle and its obtuse angle while keeping the base constant. So, lets say I have a triangle_ABC with its obtuse angle_ABC = 100°, if one increases the ange_ABC while keeping the base (segment_AC) constant, the area gets smaller. What can I use to state the relation between the angle_ABC and the area?
