(a) Here,

At first,

We have to trace the figure

Thus,

Now,

We can obseve that

The given figure is an iscoceles triangle

Hence,

It will have only one line of symmetry.

(b) Here,

At first,

We have to trace the figure

Thus,

Now,

We can obseve that

The given figure has two squares having a common vertex.

Hence,

The figure will have two lines of symmetry.

(c) Here,

At first,

We have to trace the figure

Thus,

Now,

We can obseve that

The given figure has two squares with a common centre

Hence,

The figure will have four lines of symmetry.

(d) Here,

At first,

We have to trace the figure

Thus,

Now,

We can obseve that

The given figure is an octagonal

Hence,

It will have two lines of symmetry.

(e) Here,

At first,

We have to trace the figure

Thus,

Now,

We can obseve that

The given figure is not any specific figure

Hence,

It will have only one line of symmetry.

(f) Here,

At first,

We have to trace the figure

Thus,

Now,

We can obseve that

The given figure is a four cornered figure

Hence,

It will have four lines of symmetry.
