If we take the largest acute angle,i.e.,89°,then also it does not add upto 180°.So,Two acute angle can never be supplementary. But ... (Angle) Parallel Lines and Pairs of Angles Geometry Index. (iv) Two adjacent angles always form a linear pair. Supplementary angles only add up to 180. Answer: (a) Two acute angles can be complementary to each other Answer: (i) No, because sum of two acute angles is less than 180 0. Your IP: 5.189.150.71 If two lines intersect at a point, then the vertically opposite angles are always . Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Those two angles are supplementary angles. If the two supplementary angles are adjacent (i.e. Two angles /_A are vertical (formed by two intersecting lines) and acute (smaller than 90^o). And if two acute angles are added then their sum will be less than 180 0 which contradicts the definition of the supplementary angle. One obtuse angle and one acute angle can make a pair of supplementary angles. As each of the angle is < 9 0 0.So, the sum of two acute angles is always less than 1 8 0 0.Hence they cannot form pair of supplementary angles. (iii) Two obtuse angles can form a linear pair. The two angles do not need to be together or adjacent. Although, two right angles can be supplementary because 90*2 or 90+90=180. If two lines intersect at a point, and if one pair of vertically opposite angles are acute angles, then the other pair of vertically opposite angles … They cannot be supplementary.

If two adjacent angles are complementary they form a right angle. A linear pair forms a straight angle of 180 degrees, so you have two angles whose sum is given as 180, which means they are supplementary. In fact, a linear pair forms supplementary angles. Each is a supplement of the other. Theorem 2-3. When the sum of the measures of two angles is 90°, the angles are called complementary angles. (iv) Two adjacent angles always form a linear pair. In other words, if two angles add up, to form a straight angle, then those angles are referred to as supplementary angles. Two lines intersect at a point. Can two acute angles form a pair of supplementary angles? If two angles build up to develop a straight angle, those angles are described as additional angles. 4. 3. Yes. Angles /_1 and /_2 are adjacent (share one side) and acute. Whenever two angles are complementary, each angle is said to be the complement of the other angle.
