Ncert -maths- Lines and Angles -Set A Welcome to your Ncert -maths- Lines and Angles -Set A 1. If the complement of an angle is 79º , then the angle will be of : 101º 79º 1º 11º None 2. In figure, POR is a line. The value of a is 40º 65º 45º 50º None 3. In the given figure, the value of x that will make AOB a straight line is x=36 x=25 x =30 x=40 None 4. The curve \(x + y = e ^ {xy}\) has a tangent parallel to y-axis at the point (0,1) (1,0) None (1,1) None 5. A pair of supplementary angles is 47º,133º 55º,115º 55º,11º 40º, 50º None 6. 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? ABDC is a cyclic quadrilateral. Ac is parallel to BD. ABDC is a rectangle. ∠ACQ is a right angle. None 7. An angle is 18º less than its complementary angle. The measure of this angle is 83º 81º 36º 48º None 8. The difference of two complementary angles is 30º Then, the angles are: 70º, 40º 60º, 30º 105º, 75º 20º, 50º None 9. If an angle measures 10º more than its complement, then the measure of the angle is: 35º 10º 50º 40º None 10. Angles which are both supplementary and vertically opposite are 95º 85º 90º 90º 95º 65º 100º 80º 95º 85º None 11. Draw the pairs of angles as described below. If that is not possibly, say why Angles in a linear pair which are not supplementary. Adjacent angles which are not in a linear pair. Complementary angles that are not adjacent Complementary angles that do not form a linear pair. None 12. 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 (iii) is flase (i) is false but (ii) and (iii) are true (ii) is false All (i), (ii) and (iii) are true None 13. If an angle is 60º less than two times of its supplement, then the greater angle is 100º 120º 80º 60º None 14. If the difference of two complementary angles is 10, then the smaller angle is: 45 40 50 35 None 15. The angles x and 90º −x are: vertically opposite making a linear pair supplementary complementary 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.
