The green lines are representing congruent obtuse angles. The angles are congruent because no matter how far i open my laptop either side will always be the same distance from the bottom piece. We know the angle is obtuse because the laptop top piece exceeds 90 degrees. Laptops are very useful and anyone from a student to a business man could use one. I use my laptop to type english essays often. I took this photo in my home with my phone.
