Ncert Exemplar Class 9 Maths Chapter 6 Lines And Angles

Ncert Exemplar Class 9 Maths Chapter 6 Lines And Angles Our subject experts have designed exemplar problems in accordance with the latest cbse syllabus (2023 2024) for class 9, which covers the following topics of chapter 6, lines and angles: transversal intersecting parallel lines, forming angles such as exterior angles and consecutive interior angles. this chapter is divided into two parts, and in. Ncert exemplar class 9 maths chapter exercise 6.4. question 1. if two lines intersect, prove that the vertically opposite angles are equal. solution: let the two lines ab and cd intersect at a point o. since, ray oa stands on line cd. ∴ ∠aoc ∠aod = 180° [linear pair]…. (i) since, ray od stands on line ab.

Ncert Exemplar Class 9 Maths Chapter 6 Lines And Angles The triangle is. an acute angled triangle (b) an obtuse angled triangle. (c) a right triangle (d) an isosceles triangle. if one of the angles of a triangle is 130°, then the angle between the bisectors of the other two angles can be. 50° (b) 65° (c) 145° (d) 155°. in fig. 6.2, poq is a line. the value of x is. 20° (b) 25° (c) 30° (d) 35°. Angles of a triangle are in the ratio 2:4:3. the smallest angle of the triangle is. (a) 60° (b) 40° (c) 80° (d) 20°. thinking process. use the concept, the sum of all angles in a triangle is 180°. further, simplify it and get the smallest angle. solution: (b) given, the ratio of angles of a triangle is 2 : 4 : 3. Ncert exemplar solutions for class 9 maths chapter 6 'lines and angles', urge you to work on your thinking abilities. this part has 4 activities and 35 altogether. in practice 1 there are 8 questions, in practice 2 there are 10 questions altogether, practice 3 has 10 problems and exercise 4 has 7 questions altogether. Ncert exemplar solutions for class 9 maths chapter 6 – lines and angles ⇒∠a=180 o 2 = 90 o ⇒∠a = 90 o hence, we get that the triangle is a right triangle therefore, option (d) is the correct answer. 3. an exterior angle of a triangle is 105°, and its two interior opposite angles are equal. each of these equal angles is (a) 37 ½ o (b.
