POINT
 In math, a point is represented by a dot (.) and
is used to tell exact location in space. It does
not have any length, width, or height. In other
words, it has no size.
LINE
 A line can be defined as a straight set of
points that extend in opposite directions. It has
no ends in both directions(infinite) It has no
thickness. It is one-dimensional
LINE SEGMENT
A line segment is a part of a line that has
two endpoints and a fixed length. It is
different from a line that does not have a
beginning or an end and which can be
extended in both directions.
RAY
 A ray is a part of the line having one fixed point
and the other point does not have an end. It
means that a ray has one terminating end and the
other end is extending infinitely.
ANGLE
 An angle is formed when two rays are joined
together at a common point. The common point here
is called node or vertex and the two rays are
called arms of the angle. The angle is represented
by the symbol ‘∠’.
PARALLEL LINES
 Parallel lines do not intersect each other and
distance between them is constant.
The real-life examples of parallel lines:
Railway tracks.
PERPENDICULAR LINES
 In geometry, perpendicular lines are defined
as two lines that meet or intersect each other
at right angles (90°)
CONCURRENT LINES
 When two or more lines
pass through a single
point, in a plane, they are
concurrent with each
other and are called
concurrent lines. A point
that is common to all
those lines is called
the point of
concurrency.
