If two adjacent angles are complementary they form a right angle. The bisectors of two supplementary angles are ___ perpendicular to each other. Answer: Yes . Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170° etc. asked Jun 2, 2020 in Lines and Angles by Subnam01 ( 52.0k points) lines and angles Solution: True Since, 90° + 90° = 180°, a supplementary angle. Obtuse Angle. 5. The angle supplementary to ∠1 is ∠6. Other resources: Angles - Problems with Solutions Types of angles Parallel lines cut by a transversal Test. Question 62. 3. View Full Answer Its FREE, you're just one … 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. Two angles are supplementary, if. Straight Angle (a) One obtuse angle and one acute angle (b) One reflex angle and one acute angle (c) Two obtuse angles (d) Two right angles Solution: (d) Because sum of two right angles is equal to 180°. Obtuse Angle … Note: • An acute angle is less than 90°. One obtuse angle and one acute angle can make a pair of supplementary angles. This is the only angle marked that is acute. An obtuse triangle is ___ isosceles. Two right angles are always supplementary to each other. Always. Similarly, a triangle cannot have a right angle and obtuse angle at the same time. no because supplementary means when 2 angles equal 180 degrees. Two obtuse angles form a linear pair. Take acute angle as 89 and obtuse angle as 91. One obtuse angle and one acute angle can make a pair of supplementary angles. Both of the angles are right angles. Grade 7 Maths Lines and Angles … Solution: True. • An obtuse angle … ∠ PQR is an obtuse angle because its less than 180° and greater than 90°. This means that ∠A + ∠B = 180°. As supplementary angle means 180 the sum total of 89 and 91 is 180. 4. ∠1 is an obtuse angle, and any one acute angle, paired with any obtuse angle are supplementary angles. An equilateral triangle cannot be obtuse. Question 61. • A right angle is equal to 90°. Two angles are said to be supplementary angles when they add up to 180 degrees. If one of the angles of a triangle is obtuse, the other two angles of a triangle must be acute. Sum of interior angles on the same side of a transversal with two parallel lines is 90°. An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. If the sum of two angles is an obtuse angle, at least one of the angles must be ___ a. acute. One of its angles is an acute angle and another angle is an obtuse angle. 2. but an acute angle is always less than 90 degrees, so two acute angles cannot add up to equal 180 degrees/be supplementary. As one acute angle and one obtuse angle can make two supplementary angles. The angle opposite to the obtuse angle is the longest side of the triangle. Two acute angles form a linear pair. ___ perpendicular to each other transversal with two Parallel lines is 90° angles are to.: True Since, 90° + 90° = 180°, a triangle is obtuse, other. 120°, 140°, 160°, 170° etc the other two angles of transversal...
