It's a straight line, so it has to be 180 degrees.
Conditional: If an angle is a straight angle, then its measurement is 180°.Converse: If the measure of an angle is 180°, then it is a straight angle.
An obtuse angle is a measurement of 91 degrees to 179 degrees. If it is 90 degrees, it is a right angle. If it is 1 degree to 89 degrees it is an acute. If it is 180 degrees it is a straight angle.
An obtuse angle is an angle that has a degrees measurement greater than 90 and less than 180. Anything below 90 would be considered acute. Anything 180 would be considered straight.
An angle that measures 180 degrees is a straight angle, or straight line.Line.
