FAQ (Frequently Asked Questions)

Q 1: Give an overview of the chapter Lines and angles.

Ans: Here, you will come across definitions and basic terms related to a line segment, collinear points, intersecting lines, ray, non collinear points and non intersecting lines. You shall also know about various pairs of angles such as linear pair of angles, the reflex angle, vertical opposite angle, complementary angle, adjacent angle and supplementary angles.

The chapter also gives you an idea of transversal and parallel lines with the help of the theorems to support over it. Here, the chapter also focuses upon of angle sum property of a triangle.

Q 2: What is the chapter mainly focused on?

Ans: The chapter mainly deals with: 

  • Points

  • Line segments

  • Ray

  • Collinear points

  • Non collinear points, 

  • Intersecting lines

  • Concurrent lines

  • Plane

  • Right angle

  • Acute angle

  • Obtuse angle

  • Straight angle

  • Reflex angle

  • Complete angle 

  • Equal angle

  • Vertically opposite angle

  • Bisector of an angle

  • Parallel lines

  • Adjacent angles

  • Linear pair of angles

  • Transversal of the lines

  • The angles that a transversal forms

  • interior angles that stay on the same side of the transversal

  • corresponding angles

  • Consecutive interior angles

  • Alternate interior angles

  • Scalene triangle

  • Isosceles triangle

  • Equilateral triangle

  • Acute triangle 

  • Right triangle

  • Obtuse triangle

  • Regular polygon

  • Supplementary angles

  • Complementary angles

  • Parallel lines theorems

  • Converse of theorems

  • Triangle theorems

Q 3: What is a parallelogram triangle?

Ans: Inverse sides of a parallelogram are always parallel (by definition) and because of which they will never intersect. The area of a parallelogram is twice the area of a triangle designed by one of its diagonal sides. The area of a parallelogram is also considered to be equal to the magnitude of the vector across the product of two adjoining sides.

  • Rhomboid – It is a quadrilateral whose opposite sides are adjacent and parallel sides are dissimilar, and whose angles are not always right angles.

  • Rectangle – It is a parallelogram along with four angles of equal size (i.e., right angles).

  • Rhombus – It is a parallelogram which consists of four sides with equal lengths.

  • Square – It is a parallelogram with four sides of same and equal length and angles of identical and equal size (right angles).

Q 4: Why is Vedantu an ideal study partner?
