Question
An obtuse angle has a measure that is greater than 90 degree and less than 180 degrees.  Using the law of detachment, what statment can you make if the measure of <ABC is 108 degrees?


Answer
Law of Detachment ( also known as Modus Ponens (MP) ) says that if p=>q is true and p is true, then q must be true so:

Let P be the statement if the measure of an angle is greater than 90 deg but less than 180 deg then let Q be the statement the angle is an obtuse angle. Angle ABC measures 108 deg so angle ABC is obtuse.
