Each 90 degrees rotation of the given polygon returns to the original shape, so the polygon has an order of rotational symmetry of 4.
Reflection symmetry is a type of symmetry where onehalf of the object reflects the other half of the object. Option (a) fulfils this condition.
Which of the following is a line of symmetry of the figure?
A line of symmetry is defined as the line which divides the figure into two equal mirror images
Hence from the above figure line L, line M, line N, line O are the lines of symmetry.
The net of a cone consists of the following two parts:
Which of the following figure(s) does/do not have a line of symmetry?
From the above figure we can say that figure P and Q do not have line of symmetry.
The shape will look like its original only once after you rotate the shape 360 degrees. Hence, it's rotational symmetry is 1.
What is the least number of squares that must be added, so that the line AB becomes a line of symmetry?
From the above figure minimum 2 squares should be added so that line AB becomes a line of symmetry.
Which square must be shaded so that the figure has a line of symmetry?
From the above figure, it can be shown that the square P should be shaded so that the above figure has a line of symmetry.
The shape will look like its original only once after you rotate the shape 360 degrees. Hence, it's rotational symmetry is 1.
Which of th following does not have an order 4 of rotational symmetry?
Rotational symmetry of order 4 is in (b) and (c) because in these figures, in a complete turn of 4 number of times, the object would be looking exactly the same. However, (a) only has a rotational symmetry of 1.
