Test: Symmetry & Nets - 2 - Class 5 MCQ

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.

No line can divide the parallelogram in two symmetric shapes. Thus, it does not have a reflection 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 2-dimensional shape that can be folded to form a 3-dimensional 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.

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

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.

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.
