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 Q should be shaded so that the above figure has a line of symmetry.
Which of the following does not have a reflection symmetry?
No line can divide the parallelogram in two symmetric shapes. Thus, it does not have a reflection symmetry.
Which of the following dotted lines is a line of symmetry?
The line of symmetry divides the figure into two equal mirror halves.
Thus, only dotted line N satisfies the above condition.
A net is a 2dimensional shape that can be folded to form a 3dimensional shape or a solid. The solid and the net must have the same number of faces.
Hence, the net for a cylinder is:
A square pyramid can be formed from the given net.
Which of the squares must be shaded so that the dotted line AB becomes the line of symmetry?
Line of symmetry is defined as the line that divides the figure into two equal mirror halves.
Therefore square I must be shaded so that line AB becomes the line of symmetry
What is the smallest number of squares that must be shaded so that the figure has a line of symmetry?
Line of symmetry is defined as the line that divides the figure into two equal mirror halves.
Therefore total 3 number of squares must be shaded so that the figure has a line of symmetry.
Rotational symmetry indicates that when an object is observed after some rotation it still looks the same.
Here, (a) satisfies this property.
Which of the following is the line of symmetry of the given figure?
Line of symmetry is defined as the line that divides the figure into two equal mirror halves.
Here, only CD satisfies the above condition.
The shape will look like its original only once after you rotate the shape 360 degrees. Hence, it's order of rotational symmetry is 1.
