Ncert -maths- Lines and Angles -Set A Welcome to your Ncert -maths- Lines and Angles -Set A 1. The curve \(x + y = e ^ {xy}\) has a tangent parallel to y-axis at the point None (1,0) (0,1) (1,1) None 2. An angle is 18º less than its complementary angle. The measure of this angle is 83º 36º 81º 48º None 3. 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? ∠ACQ is a right angle. Ac is parallel to BD. ABDC is a cyclic quadrilateral. ABDC is a rectangle. None 4. If the difference of two complementary angles is 10, then the smaller angle is: 45 40 35 50 None 5. If an angle measures 10º more than its complement, then the measure of the angle is: 40º 35º 10º 50º None 6. If the complement of an angle is 79º , then the angle will be of : 101º 1º 11º 79º None 7. The difference of two complementary angles is 30º Then, the angles are: 105º, 75º 70º, 40º 20º, 50º 60º, 30º None 8. A pair of supplementary angles is 40º, 50º 55º,115º 47º,133º 55º,11º None 9. The angles x and 90º −x are: making a linear pair supplementary vertically opposite complementary None 10. In the given figure, the value of x that will make AOB a straight line is x=25 x=36 x =30 x=40 None 11. Angles which are both supplementary and vertically opposite are 95º 85º 95º 65º 90º 90º 95º 85º 100º 80º None 12. 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 13. If an angle is 60º less than two times of its supplement, then the greater angle is 100º 120º 80º 60º None 14. 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 (i) is false but (ii) and (iii) are true (ii) is false (iii) is flase All (i), (ii) and (iii) are true None 15. In figure, POR is a line. The value of a is 50º 40º 65º 45º 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.
