CBSE Class 7 is no doubt a very valuable class and the last class of your school life. We have provided Lines and Angles Class 7 Maths MCQs Questions with Answers to help students understand the concept very well. (i) ∠PSC = ∠RSF = 50° [Vertically opposite angles] (d) 105°, 75° As ∠RSP and ∠QPD are corresponding angles and are not equal. ∴ ∠PQR + ∠RQO = 180° [Linear pair] Question 84. Amisha makes a star with the help of line segments a, b, d, e and f, in which a || d, b || e and c || f. Chhaya marks an angle as 120° as shown in figure, and asks Amisha to find the ∠x, ∠y and ∠z. Lines l and m are parallel, P is transversal and x = 30°. Thus, a = 50° and b = 130°. Since, AF || ED and FD is a transversal. ∴ ∠BCD = ∠CDT [Alternate interior angles] ∴ y = 2 × 18° = 36° Solution : ∴ ∠QRT = ∠RQU [Alternate interior angles] In the given figure, POR is a line. (a) It is given that, angles P and 0 are supplementary. NCERT Solutions for Class 7 Maths Chapter 5 Lines and Angles Exercise 5.1 and Exercise 5.2 in English Medium and Prashnavali 5.1 and Prashnavali 5.2 in Prashnavali to study online or download in PDF file for offline free to use. Solution : In the given figure, if PQ || RS and QR || TS, then the value of a is 90° – x = 62° It is not necessary that uncommon arms must be always opposite rays. (a) 20°, 50° Question 62: (d) Sum of the given angles Solution : Solution : Then, sum of two right angles will be (90°+ 90°) = 180°. Thousands of Students are looking for Lines and Angles formulas for class 7. Solution: Since, PQ || RT and RQ is transversal. ⇒ x = 720° – 4x (b) 67° ⇒ ∠Q = 180° – 60° = 120°, Question 13. NCERT Solutions for Class 7 Maths … Solution : (b) 135° Solution: In the given figure, two parallel lines l and m are cut by two transversals p and 4. Thus, both the angles are of 83°. Two adjacent angles always form a linear pair. (b) how many types of angles are formed? NCERT Exemplar Class 7 Maths Solutions Chapter 5: Lines and angles In this chapter you will learn about complementary angles, adjacent angles, perpendicular lines and parallel lines. This chapter deals with the basics of Geometry, parallel lines and transversal, pair of lines, angles and its types, Related angles and interior and exterior angles of triangles. ∴ y = 180° – 80° = 100° Since, QP || RS and PR is transversal. = 60° Solution: (a) Let an angle be x. Now, SOT is a straight line If ∠ABC = 46°, then ∠ABP is equal to RD Sharma Class 11 Solutions Free PDF Download, NCERT Solutions for Class 12 Computer Science (Python), NCERT Solutions for Class 12 Computer Science (C++), NCERT Solutions for Class 12 Business Studies, NCERT Solutions for Class 12 Micro Economics, NCERT Solutions for Class 12 Macro Economics, NCERT Solutions for Class 12 Entrepreneurship, NCERT Solutions for Class 12 Political Science, NCERT Solutions for Class 11 Computer Science (Python), NCERT Solutions for Class 11 Business Studies, NCERT Solutions for Class 11 Entrepreneurship, NCERT Solutions for Class 11 Political Science, NCERT Solutions for Class 11 Indian Economic Development, NCERT Solutions for Class 10 Social Science, NCERT Solutions For Class 10 Hindi Sanchayan, NCERT Solutions For Class 10 Hindi Sparsh, NCERT Solutions For Class 10 Hindi Kshitiz, NCERT Solutions For Class 10 Hindi Kritika, NCERT Solutions for Class 10 Foundation of Information Technology, NCERT Solutions for Class 9 Social Science, NCERT Solutions for Class 9 Foundation of IT, PS Verma and VK Agarwal Biology Class 9 Solutions, NCERT Solutions for Class 10 Science Chapter 1, NCERT Solutions for Class 10 Science Chapter 2, Periodic Classification of Elements Class 10, NCERT Solutions for Class 10 Science Chapter 7, NCERT Solutions for Class 10 Science Chapter 8, NCERT Solutions for Class 10 Science Chapter 9, NCERT Solutions for Class 10 Science Chapter 10, NCERT Solutions for Class 10 Science Chapter 11, NCERT Solutions for Class 10 Science Chapter 12, NCERT Solutions for Class 10 Science Chapter 13, NCERT Solutions for Class 10 Science Chapter 14, NCERT Solutions for Class 10 Science Chapter 15, NCERT Solutions for Class 10 Science Chapter 16, CBSE Previous Year Question Papers Class 12, CBSE Previous Year Question Papers Class 10. 3 and 4 only Maths NCERT Solutions for Class 7 Maths Chapter 5 lines...
