HA LV ES R O R IR M Do you like to hear Amina’s story ?

Tit for Tat One day Amina met a painter. Can you make my picture? After a while the painter showed her the picture. But this is only half ! Amina! How do you like it? Now can I have my money? The other half is exactly the same. So just put a mirror to get the complete picture. Amina gave him a hundred-rupee note. But this is only half the money ! Yes, sure! I charge Rs 200 for it. The other half is exactly the same. So just put a mirror next to the note to get the full money! Ha, ha!

The painter had made many such pictures in which he drew only one half of the things. Draw the other half of these pictures and find out what these things are. Try doing it with a mirror. Can we repeat the painter's trick, while drawing pictures of the following? If you ask the painter to draw things which cannot be divided into two similar mirror halves, then he cannot play the trick. Draw three more such things which do not have similar mirror halves.

…………. . ……………… ……………………… G ……. . ………… Observe the pictures/figures. Does the dotted line divide each picture into two similar mirror halves ?

Can you guess these letters from their halves?

Guess the words by looking at their halves.
