FAQs on What are Shapes? Video Lecture - Class 2
| 1. What are Shapes? |  |
Ans. Shapes are defined as the geometric figures that have a definite contour or boundary. They can be two-dimensional or three-dimensional and can be classified based on their properties such as the number of sides, angles, and vertices. Examples of shapes include circles, squares, triangles, rectangles, and polygons.
| 2. What are the different types of shapes? | |
Ans. Shapes can be broadly classified into two categories: 2D shapes and 3D shapes. 2D shapes are flat figures that are limited to only length and width, such as squares, triangles, circles, and rectangles. 3D shapes, on the other hand, have depth in addition to length and width and include figures such as cubes, spheres, pyramids, and cylinders.
| 3. How are shapes used in mathematics and everyday life? | |
Ans. Shapes are an essential part of mathematics and have various applications in everyday life. In mathematics, shapes are used to teach geometry, measurement, and spatial reasoning. In everyday life, shapes are used in construction, architecture, art, and design. They are also used in cooking, where different shapes of utensils and molds are used to prepare different types of food.
| 4. How can one identify and classify shapes? | |
Ans. Shapes can be identified and classified based on their properties. For example, the number of sides, angles, and vertices can be used to identify and classify 2D shapes. Similarly, the number of faces, edges, and vertices can be used to identify and classify 3D shapes. In addition, one can also use visual recognition and pattern recognition to identify and classify shapes.
| 5. How can one teach shapes to children? | |
Ans. To teach shapes to children, one can use various methods such as visual aids, manipulatives, and games. Visual aids such as posters, flashcards, and videos can be used to introduce and reinforce the concept of shapes. Manipulatives such as blocks, puzzles, and shape cutouts can be used to help children understand the properties and characteristics of different shapes. Games such as shape matching, scavenger hunts, and shape bingo can make learning about shapes more fun and engaging for children.

0:0:0: basic shapes
0:0:3: there are a number of shapes all around
0:0:7: us
0:0:8: but the four basic shapes
0:0:11: are
0:0:12: triangle
0:0:15: square
0:0:18: rectangle
0:0:21: and circle
0:0:24: this is a square
0:0:27: it has
0:0:29: four sides
0:0:30: and four corners
0:0:35: let us now list out the things around us
0:0:39: that are square in shape
0:0:42: a clock
0:0:45: a photo frame
0:0:48: a window
0:0:52: let us now make a square
0:0:55: through paper
0:0:56: folding step 1
0:0:59: take a paper
0:1:1: and fold it as shown
0:1:5: step 2
0:1:7: cut the shaded portion
0:1:10: step 3
0:1:12: now unfold the paper
0:1:16: we get a square
0:1:19: the dotted line is a diagonal obtained
0:1:23: by joining the respective opposite
0:1:27: corners
0:1:30: there are two diagonals in a square
0:1:36: to compare the sides of the square fold
0:1:40: the paper as shown
0:1:44: all sides of a square
0:1:47: are equal
0:1:50: measure the diagonals with a thread
0:1:55: the diagonals are also equal
0:2:0: rectangle
0:2:3: this is a rectangle
0:2:7: it has
0:2:8: four sides
0:2:10: and four corners
0:2:13: to measure the sides of the rectangle
0:2:18: fold its opposite sides
0:2:22: what do you observe
0:2:25: the sides coincide
0:2:28: so
0:2:29: opposite sides
0:2:31: are equal
0:2:35: did for the square
0:2:37: make the diagonals in the rectangle
0:2:41: and measure the diagonals
0:2:44: using a thread
0:2:47: in a rectangle also
0:2:50: diagonals are equal
0:2:54: now let us list out the things around us
0:2:58: which are rectangular in shape

0:3:11: a laptop
0:3:14: triangle
0:3:16: this is a triangle
0:3:21: let us make a triangle
0:3:23: through paper folding
0:3:27: take a paper
0:3:29: and cut it along its diagonal
0:3:33: we get
0:3:35: two triangles
0:3:39: a triangle has
0:3:41: three sides
0:3:44: it also has three corners
0:3:49: now let us list out things around us
0:3:53: which are triangular in shape
0:3:58: samosa
0:4:0: cone ice cream
0:4:4: circle
0:4:7: this
0:4:8: is a circle
0:4:10: a circle
0:4:11: is a closed curve
0:4:14: it has no corners
0:4:19: let us learn to draw a circle
0:4:22: using
0:4:23: pencil
0:4:24: and thread
0:4:28: tie one end of the thread to the pencil
0:4:32: as shown
0:4:35: press the other end of the thread on the
0:4:38: paper
0:4:40: and draw the curved line
0:4:42: with the pencil
0:4:44: we get a circle
0:4:48: this is the center
0:4:50: of the circle
0:4:53: it has no corners
0:4:58: now let us list out the things around us
0:5:2: which are circular in shape
0:5:6: disk

0:7:16: and other things
0:7:20: let us prepare some 10 grams
0:7:22: with these five pieces
0:7:27: let us do this figure
0:7:31: one
0:7:32: two
0:7:34: three
0:7:36: four
0:7:38: five
0:7:41: let us do the next one
0:7:44: one
0:7:46: two
0:7:48: three
0:7:50: four
0:7:54: in this figure also
0:7:56: we need only four tangrams
0:8:0: one
0:8:2: two
0:8:4: three
0:8:6: four
0:8:10: this figure needs
0:8:12: 5 10 grams
0:8:15: 1
0:8:17: 2
0:8:18: 3
0:8:20: 4
0:8:22: and 5.

0:8:55: all the five triangles
0:8:59: one
0:9:1: two
0:9:2: three
0:9:4: four
0:9:6: five
0:9:9: pull a piece of thread tightly between
0:9:13: your hands as shown
0:9:16: it gives you
0:9:17: a straight line
0:9:20: now bring the two hands closer
0:9:23: it gives you
0:9:25: a curved line
0:9:30: curved lines and straight lines
0:9:33: can be drawn
0:9:34: with the help of dots
0:9:38: look at these designs
0:9:42: we call them
0:9:43: column
0:9:48: tessellation
0:9:50: a tessellation is created
0:9:53: when a shape is repeated over and over
0:9:57: again
0:9:59: covering a plane
0:10:1: without any gaps
0:10:3: or overlaps
0:10:6: triangles
0:10:7: squares
0:10:9: hexagons
0:10:10: are the regular polygons tesolate
0:10:13: in the plane

0:10:45: five equal sides
0:10:48: heptagons
0:10:50: seven equal sides
0:10:54: although pentagons and heptagons are
0:10:58: regular polygons they do not tessellate
0:11:4: solid shapes
0:11:6: solid shapes have three characteristics
0:11:10: they are
0:11:12: the length
0:11:14: breadth
0:11:15: and height
0:11:17: these are also called
0:11:19: 3d objects
0:11:23: let us see some of the solid shapes
0:11:28: what is this
0:11:30: this is a cube
0:11:33: and this
0:11:34: is a cuboid

0:14:59: the flag post
0:15:0: is at the
0:15:2: dash
0:15:3: of the school
0:15:5: in front
0:15:7: or center
0:15:10: look at this picture
0:15:13: now let us discuss
0:15:15: the spatial relationship among the
0:15:18: persons

0:15:44: and the daughter
0:15:47: the clock
0:15:49: is
0:15:50: above the
0:15:52: television the television
0:15:56: is
0:15:57: on
0:15:58: the table
0:16:17: you
0:0:3: there are a number of shapes all around
0:0:7: us
0:0:8: but the four basic shapes
0:0:11: are
