Two angles are said to be complementary angles, if their sum is 90°. (iv) When two lines intersect opposite angles are supplementary. 5. 50° 72° 108° 120° 4.Two adjacent, supplementary angles form a(n) _____. always sometimes never 6.Two adjacent angles whose exterior sides are opposite rays are complementary. Obtuse vertically opposite angles. straight angle. Then, x + 45° = 90° ⇒ x =90° – 45° = 45° Question 56: Question 55: An angle is 45°. Adjacent angles Supplementary angles Bisecting angles Complementary angles Angle ABC is adjacent to angle CBD. 2. Complementary angles always have positive measures. Answer: (d) When a transversal cuts two lines such that pairs of interior angles on the same side of the transversal are complementary, then the lines have to be parallel Question 31. Your are correct in that statement. 3. Solution : 45° Let x be the required angle. Reflex angle: An angle whose measure is more than 180° but less than 360° is called a reflex angle. Obtuse angle: An angle whose measure is more than 90° but less than 180°, is called an obtuse angle. Explanation: As the vertically opposite angles are equal. When two angles are adjacent, then their sum is the angle formed by their non-common arms. Unequal supplementary angles. Click hereto get an answer to your question ️ Consider the following statements : When two straight lines intersect, (i) adjacent angles are complementary (ii) adjacent angles are supplementary (iii) opposite angles are equal (iv) opposite angles are supplementary. In a parallelogram, the angles add up to 360˚. As the adjacent angles form a linear pair and they are supplementary. Step-by-step explanation: So complementary angles is 90 and both are same we get equation x … Answer (i) Obtuse vertically opposite angles means greater than 90° and equal ∠AOD = ∠BOC. Three angles or more angles whose sum is equal to 90 degrees cannot also be called complementary angles. it is composed of two acute angles measuring less than 90 degrees. 4. _____ are two angles that add to equal 180°. Its complementary angle will be_____. Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap. Adjacent Angles. Because: they have a common side (line CB) they have a common vertex (point B) What Is and Isn't an Adjacent Angle. Adjacent angles that d° n°t f°rm a linear pair. This statement is correct. Two adjacent complementary angles are equal then angles are 2 See answers nishuyadav550 nishuyadav550 Answer: 180 degree. It is just a complete one angle. If a ray stands on a line, then the sum of adjacent angles formed is \(180^{\circ}\) If the sum of two adjacent angles is \(180^{\circ}\), then they are called a linear pair of angles. Since there are two pairs of angles and one of each pair is on each side, adjacent angles are supplementary (their sum makes 180˚) The following diagram explains: Common examples of complementary angles are: Two angles measuring 45 degrees each. (iii) When two lines intersect opposite angles are equal. Complementary angles: Two angles are said to be complementary, if the sum of their measures is 90o. right angle obtuse angle line 5.When two lines are cut by a transversal, if the alternate interior angles are equal in measure, then the lines are parallel. In a parallelogram, opposite angles have equal lengths, and so in each parallelogram there are two pairs of equal angles. ShrayBohra ShrayBohra Answer: 45. Find an answer to your question Two adjacent complementary angles are equal, then angles are (a) 90°, 90° (b) 75°, 75° (c) 30°,30° (d) 45°, 45° thrivedha9 thrivedha9 05.10.2020 This statement is … Adjacent complementary angles. Hence, if two angles are complementary, then each angle cannot be more than 90°. Equal supplementary angles. 1.
