Three angles cannot be supplementary. definition of supplementary angles is two angles that when added together equal 180degrees definition of acute angle: any angle who's degree is … corresponding: 1&5, 2&6, 3&7, 4&8 alt. Is this true or false? (iii) Two obtuse angles can form a linear pair. A pair of vertical angles can be supplementary. Acute angles are those angles which are less than 90°. Answer. Because acute angles add up to 0 through 90. Two acute angles cannot be supplementary (sum of them should equal to 180o) because each of them is smaller than 90o. By definition, acute angles are the angles that measure the angle greater than 0° and less than 90°. Here, the two adjacent angles are supplements. Angles are usually measured in degrees and denoted by \({\circ}\) (the degree symbol), which is a measure of circularity or rotation.. Angles are a part of our day to day life. Vertical angles must have the same measure. C. Supplementary angles are linear pairs. have a common vertex and share just one side), their non-shared sides form a straight line.
