Two acute angles cannot be supplementary (sum of them should equal to #180^o#) because each of them is smaller than #90^o#. Question 59. The nonadjacent rays of two adjacent, complementary angles are perpendicular. If the sum of two angles is 180 degrees then they are said to be supplementary angles, which forms a linear angle together. Can an acute angle be adjacent to an obtuse angle? Those two angles are adjacent angles separated by a line in between. If you add two acute angles in which each angle is large as possible, its sum will be less than 180°. supplimentry means when 2 angles add up to 180 degress (two right angles cant be used as acutes). Two acute angles can be only complementary, as they add up to 90°. Although, two right angles can be supplementary because 90*2 or 90+90=180. Conjecture: They are both acute angles. No, since obtuse angles must be greater than 90 degrees and less than 180 degree, any two obtuse angles would add up to greater than 180 degrees. As one acute angle and one obtuse angle can make two supplementary angles. This is a right angle. This also satisfies the condition that one angle is three times the other. False - 10 and 30 degrees.
