I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.
A triangle is 180 degrees. Depending on their angles: Right Angle - 90 degrees
Acute Angle - less than 90 degrees and Obtuse Angle greater than 90 degrees and under 180 degrees. Hope that helps.
