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
