### Similarity

If two objects are similar, they would have the same shape and proportion.

#### Theorems to determine similarity.

If three angles of a triangle are equal to three angles of another triangle, then these triangles are similar and the sides opposite to equal angles are proportional.
If two angles of a triangle are equal to two angles of another triangle, then these triangles are similar.
If three sides of a triangle are proportional to three sides of another triangle, then these triangles are similar
If two sides of a triangle are proportional to two sides of another triangle and their including angles are equal then these triangles are similar.

#### Main points to remember.

The line joining the midpoints of two sides of a triangle is parallel and half as long.
The centroid of a triangle divides the median into 2 : 1

### ARROW AND THE SONG

The Arrow and the Song

I shot an arrow into the air,
It fell to earth, I knew not where;
For, so swiftly it flew, the sight
Could not follow it in its flight.

I breathed a song into the air,
It fell to earth, I knew not where;
For who has sight so keen and strong
That it can follow the flight of song?

Long, long afterward, in an oak
I found the arrow, still unbroken;
And the song, from beginning to end,
I found again in the heart of a friend.
By Henry W. Longfellow.

### DIFFERENT TYPES OF MUTATIONS

 1 DNA base substitution, insertion, and deletion 2 unequal crossing-over and related structural modifications of chromosomes 3 partial or complete gene inversion and duplication 4 irregular numbers of chromosomes

### MUTATION

MUTATION

MUTATION IS THE PERMANENT CHANGE IN THE DNA SEQUENCE OF A GENE.
MUTATIONS MAY LEAD TO MISSING OR MALFORMED PROTEINS WHICH MAY LEAD TO DISEASES.MUTATIONS HAPPENS DURING CELL DIVISION WHEN THE DNA GETS DUPLICATED. A FEW TYPES OF MUTATIONS ARE BAD FOR US BUT SOME MUTATIONS ARE BENEFICIAL FOR US,THEY CAN CREATE GENETIC DIVERSITIES. CANCER USUALLY OCCURS DUE TO THE MULTIPLE MUTATIONS INSIDE A SINGLE CELL.

### CAN WE TRAVEL IN THE SPEED OF LIGHT?

THE ANSWER WHICH IS AVAILABLE TODAY IS NO.SCIENTISTS BELIEVE THAT NOTHING CAN TRAVEL IN THE SPEED OF LIGHT. THEY SAY THIS BECAUSE THERE IS NO ENOUGH ENERGY IN THE WHOLE OF THE UNIVERSE TO MAKE EVEN A SMALLEST THING TO REACH SUCH A SPEED.

### A SHORT SPEECH ON HUMILITY

RESPECTED JUDGES,TEACHERS AND MY DEAR FRIENDS,

IN THE ERA IN WHICH THE WHY ME FEELING IS ARISING,HUMILITY IS ONE OF THE MORAL VALUES WHICH IS CEASING DAY BY DAY.

FIRST OF ALL HUMILITY IS A TRUE SIGN OF GREATNESS. ALMOST ALL GREAT PERSONALITIES ARE HUMBLE ONES.IF ONE IS GREAT,HE SHOULD HAVE HUMILITY TO THE GREATEST EXTENT.

ONLY A PERSON WITH HUMBLE HEART CAN ATTAIN THE PEAKS OF EXCELLENCE AND PERFECTION. HE CAN ONLY LEARN ANYTHING WORTHWHILE IN HIS LIFE.

MAY THE WORLD BECOME A BETTER PLACE WITH PERSONS OF HUMBLE BEHAVIOUR.

THANK YOU

### DAFFODILS BY WILLIAM WORDSWORTH

I wandered lonely as a cloud
That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.

Continuous as the stars that shine
And twinkle on the milky way,
They stretched in never-ending line
Along the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.

The waves beside them danced; but they
Out-did the sparkling waves in glee:
A poet could not but be gay,
In such a jocund company:
I gazed--and gazed--but little thought
What wealth the show to me had brought:

For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.
