If the sum of two angles are 180o then the angles are said to be supplementary angles,. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. If two angles build up to develop a straight angle, those angles are described as additional angles. If the two supplementary angles are adjacent (i.e. (v) Pair of vertically opposite angles are always supplementary. (vii) If two lines are cut by a transversal, (i) Two obtuse angles can be supplementary. (iii) Two obtuse angles can form a linear pair. Because acute angles add up to 0 through 90. If we add 60° and 70°, we get 60°+ 70° = 130° <180° Hence, two acute angles cannot form a pair of supplementary angles. 2. By definition, acute angles are the angles that measure the angle greater than 0° and less than 90°. Answer: (i) No, because sum of two acute angles is less than 180 0.

Both angles form a direct angle, such that if one angle is x, the other the angle … Angle 3 and angle 4 form a linear pair. When the sum of two angles is 180°, then the angles are known as supplementary angles. If two adjacent angles are complementary they form a right angle. An acute angle is an angle whose measure of degree is more than zero degrees but less than 90 degrees. When the sum of the measures of two angles is 90°, the angles are called complementary angles. (vii) If two lines are cut by a transversal, Those two angles are supplementary angles. Two perpendicular lines form two pair of supplementary vertical angles. If we add two angles which are less than 90°, we get the result less than 180°, e.g. ∠ θ is an acute angle while ∠ β is an obtuse angle.

If we add two angles which are less than 90°, we get the result less than 180°, e.g. 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. Two acute angles cannot be supplementary (sum of them … Think, Discuss and Write As each of the angle is < 90 0 .So, the sum of two acute angles is always less than 180 0 .Hence they cannot form pair of supplementary angles. As if both angles are 89° and 89°, even then they cannot make the sum 180°. If the exterior sides of 2 adjacent acute angles are perpendicular, then the angles are complementary. Example 2: the angles form a line (linear pair) therefore they are supplementary Example 3: the angles can be non-adjacent as long as their sum is 180° 110°+ 70° = 180° The sum is 180° therefore they are supplementary. When 2 lines intersect, they form two pairs of these. There are currently no name for 2 angles that add up to 270 degrees but Explementary Angles are the name for a pair of angles that adds up to 360 degrees, even if an angle is more than 180 degrees Hope that this is helpful (3 votes) See 2 more replies Why? Sum of interior angles on the same side of a transversal with two parallel lines is 90°. Those two angles … Solution : Acute angles are those angles which are less than 90°. Two angles /_A are vertical (formed by two intersecting lines) and acute (smaller than 90^o). The measure of angle 3 is four more than three times the measure of angle 4. • 5. So my question is if both angle 1 and 2 must equal 90 degrees each? Supplementary angles only add up to 180. Solution: No, two acute angles cannot form a pair of supplementary angles. … Angles /_1 and /_2 are adjacent (share one side) and acute.
