Geometrical Shapes and Solids
Category : 4th Class
How to identify the figure of largest perimeter?
If after observation, we get that length does not changes but width changes then figure having largest width have largest perimeter.
In curved images, figure which has maximum curves have largest length.
How to identify the symmetrical figure?
If a line divides any figure in identical parts, then figure is symmetrical and line is called line of symmetry.
How to count the geometrical shapes?
Identify the shapes and solids by their names and images to count in the figure.
How to identify the net of a cube?
It should have 6 faces and when folded, it forms a box.
1. Is the dotted line in the figure below a line of symmetry?
(c) can't say
(d) None of these
2. How many horizontal lines are there in the given letter?
Figure is symmetrical about the dotted line. Number of horizontal lines on the left of dotted line are AB, CD, EF, GH that is 4.
Therefore total number of horizontal lines = 8
3. How many letters given below have at least one line of symmetry?
Dotted lines are lines of symmetry.
