Ncert -maths- Lines and Angles -Set A Welcome to your Ncert -maths- Lines and Angles -Set A 1. Draw the pairs of angles as described below. If that is not possibly, say why Complementary angles that are not adjacent Angles in a linear pair which are not supplementary. Complementary angles that do not form a linear pair. Adjacent angles which are not in a linear pair. None 2. In the given figure, the value of x that will make AOB a straight line is x=40 x =30 x=36 x=25 None 3. In figure, POR is a line. The value of a is 65º 50º 45º 40º None 4. The angles x and 90º −x are: complementary vertically opposite supplementary making a linear pair None 5. In a pair of adjacent angles, (i) vertex is always common,(ii) one arm is always common, and(iii) uncommon arms are always opposite rays Then (ii) is false (iii) is flase All (i), (ii) and (iii) are true (i) is false but (ii) and (iii) are true None 6. A pair of supplementary angles is 55º,115º 47º,133º 40º, 50º 55º,11º None 7. Angles which are both supplementary and vertically opposite are 95º 85º 90º 90º 95º 85º 100º 80º 95º 65º None 8. If the complement of an angle is 79º , then the angle will be of : 79º 101º 11º 1º None 9. The curve \(x + y = e ^ {xy}\) has a tangent parallel to y-axis at the point None (1,1) (0,1) (1,0) None 10. If an angle measures 10º more than its complement, then the measure of the angle is: 10º 50º 40º 35º None 11. Two circles APQC and PBDQ intersect each other at the points P and Q and APB and CQD are two parallel straight lines. Then only one of the following statements is always true. Which one is it? Ac is parallel to BD. ABDC is a rectangle. ∠ACQ is a right angle. ABDC is a cyclic quadrilateral. None 12. If the difference of two complementary angles is 10, then the smaller angle is: 45 35 50 40 None 13. If an angle is 60º less than two times of its supplement, then the greater angle is 80º 60º 100º 120º None 14. An angle is 18º less than its complementary angle. The measure of this angle is 48º 83º 81º 36º None 15. The difference of two complementary angles is 30º Then, the angles are: 105º, 75º 20º, 50º 60º, 30º 70º, 40º None Time's up Please Share This Share this content Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Opens in a new window Leave a Reply Cancel replyCommentEnter your name or username to commentEnter your email address to commentEnter your website URL (optional) Save my name, email, and website in this browser for the next time I comment.
