# two supplementary angles are always obtuse angles

Lv 7. Question 8. 3 Answers. Can two right angles be supplementary? Sometimes, the measures of these angles form a special relationship. adjacent angles Adjacent angles are next to each other. Since an obtuse angle angle has degree greater than 90, two obtuse angles produce a sum that is greater than 180 degrees which is impossible. One of its angles is an acute angle and another angle is an obtuse angle. If the two supplementary angles are adjacent (i.e. 3. Note: (a) Two acute angles cannot be supplement of each other. Anonymous. Two adjacent, supplementary angles form a line. 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. is this always true sometimes true or never true.? always. 0 0? Is its complementary angle greater than 45° or equal to 45° or less than 45°. Is its complementary angle greater than 45° or equal to 45° or less than 45°? Solution : False If two angles are supplementary angles, then it is not necessary that they are always obtuse angles. Question 8. ∠ PQR is an obtuse angle because its less than 180° and greater than 90°. supplementary angles Two (or more) angles are supplementary if they add up to . Yes ! As one acute angle and one obtuse angle can make two supplementary angles. Both of the angles are right angles. | EduRev Class 9 Question is disucussed on EduRev Study Group by 1037 Class 9 Students. EASY. Straight Angle & Its Properties. The angle inside a triangle add up to 180 degrees. In the adjoining figure: Is ∠1 adjacent to ∠2 ? Any triangle can have only one obtuse angle. Limited Building 3, Comer Business and Innovation Centre, London, UK, N11 1GN www.neptunedocs.co.uk Two perpendicular lines form two pair of supplementary vertical angles. 2. An angle is greater than 45°. Such angles are called a linear pair of angles. Home » lines and angles questions pdf. Supllementary angles add to 180 degrees, exactly. The remaining angle measure of the triangle would have to be negative in that case. Two angles together are angle pairs. Two adjacent, supplementary angles form a right angle obtuse angle line. Question 61. In the diagram below the two angles are adjacent, but they do not add up to . And I'll start reusing letters. Two supplementary angles are always obtuse angles. (viii) If two lines are cut by a transversal, then each pair of alternate interior angles are equal. You have supplementary angles. Answer Save. Is its complementary angle greater than 45° or equal to 45° or less than 45°. Question 60: Two right angles are always supplementary to each other. Two angles are said to be supplementary angles when they add up to 180 degrees. true/false - 21556040 Supplementary angles could be congruent. Two right angles are always supplementary. Each angle is called the supplement of the other. Two right angles are always supplementary to each other. It seems as if they form an obtuse angle, which is shaded red. And you have another angle that looks like this. Solution: Its complementary angle is less than 45°. (ii) No, because sum of two obtuse angles is more than 180 0. Two obtuse angles cannot be supplementary. Solution: True. always. These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle. (iv) Two adjacent angles always form a linear pair. A right angle by definition is 90 degrees. Complementary angles sum to 180°. True/False (1) Pair of adjacent angles always form a linear pair (2) Supplementary angle of acute angle is always obtuse angle (3) 45° is that angle which is equal to its complement. 6.Two adjacent angles whose exterior sides are opposite rays are complementary. This means that ∠A + ∠B = 180°. In other geometries such as spherical geometry, triangles can have two obtuse angles. In the adjoining figure: Is ∠1 adjacent to ∠2 ? In Euclidean Geometry, a triangle always has an angle sum of 180 degrees. One special relationship is called complementary angles. False. Solution: True Since, 90° + 90° = 180°, a supplementary angle. Question 62. And that you have another angle. In other words, when complementary angles are put together, they form a right angle (90 degrees). never Is ∠ AOC adjacent to ∠ AOE ? In other words, if two angles add up, to form a straight angle, then those angles are referred to as supplementary angles. Answer. 1 month ago. Or a 40º-70º-70º for example.
