yeah
yeah
yeah
at the end of this module you will be
able to understand one-dimensional
two-dimensional and three-dimensional
figures the disease faces and edges of
the three-dimensional figures
socket suddenly look up looking at the
window
it was still dark he looked at the clock
it was 3am he had be doing this the
whole night he slept back again
once again he voca but this time he
could see the sky turning bride that
sunlight
he looked at the clock and it was 15
minutes past six
he threw his bed cover the side and ran
to his father he reminded his father
that he had promised to take him to the
news
I demand movie his father handed him
over to tickets at the movie
spider-man
it said sunday morning show the amazing
spider-man 3d suck it was very much
excited but he was confused by the term
3d on the ticket socket asked his father
what 3d represented
sockets father explained him about
dimensions as follows
in our day to day life we come across
several objects which have different
shapes and sizes
one thing comment about most of these
objects is that they all have some
length breadth and hide objects or
figures have only length and known as
one-dimensional objects for example a
line is a one dimensional figure array
is a one dimensional figure figures
having some length
and breaths
and known as do dimensional figures
these figures can be easily represented
on the plane that is why they're called
plane figures example squared circle
triangle are two dimensional figures
objects and shapes having length breadth
and height and known as
three-dimensional objects and shapes
some of the three-dimensional objects
are too boy
q
gold Selinda
fear etc all the three-dimensional
objects have faces edges and vertices
leak honest but for some shape a call
it's her disease the line segments of
its skeleton its edges and it's flat
surfaces are its faces the cuboid has
six rectangular faces
12 edges
mmm
and ate the disease
q also has six square faces
12 edges
yeah
and eight vertices
a triangular pyramid has four faces
yeah
six edges
yeah
and forward disease
a cylinder has no buttocks
to secular faces
one could rectangular face
yeah
yeah
and to come edges
a code
has one vertex
one circular face
concord face
and one good edge the sphere has no
politics no edge and one could face
in this module we have dared
the circle the square the rectangle the
quadrilateral and the triangle are
examples of plane figures the cube that
you . the sphere the cylinder the cone
and experiment are examples of solid
shapes playing figures are two
dimensions
- D and the solid shapes are of three
dimensions 3d the corners of a solid
shape called it's the disease the line
segments of its skeleton its edges
and it's flat surfaces it's a thesis
