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