LINES AND ANGLES CBSE Class 9

LINES AND ANGLES
  • A line is a one-dimensional figure that has no
    thickness and which extends infinitely in both
    the directions. A line segment is a part of a
    line whose both ends are fixed.
  • Two   angles are adjacent, if they have a common
    vertex, a common arm and their non-common arms
    are on different sides of the common side. A pair
    of adjacent angles, whose non-common sides lie
    opposite to each other at an angle of 180, is
    called a linear pair. A pair of non-adjacent
    angles formed by the intersection of two straight
    lines is called vertically opposite angles.
    Vertically opposite angles are equal.
  •  Parallel lines are coplanar and they do not
    intersect each other. Transversal intersects two
    or more lines. If a transversal intersects a pair
    of parallel lines, then pair of vertically
    opposite angles is equal. pair of alternate
    angles is equal. consecutive interior angles are
    supplementary. corresponding angles are equal
