140 degrees
A 140 degree angle is about half way between a 90 degree angle, which has lines that are perpendicular to each other, and a 180 degree angle, which is a straight line. A 140 degree angle is an obtuse angle which has a line a little over half way between the 90 degree and 180 degree angles.
A 140 degree angle would be called an obtuse angle.
No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.
Any polygon can have a 50-degree angle. It doesn't have to, but it can.

Any polygon can have a 40-degree angle. It doesn't have to, but it can.
Any polygon can have a 50-degree angle. It doesn't have to, but it can.
Any polygon can have a 130-degree angle. It doesn't have to, but it can.
In a right triangle the greatest angle is 90 degrees.
