Question

For spreading the message 'save girl child save future' a rally was organized by some students of a school. they were given triangular cardboard piece.PQR which they divided in to two parts by drawing the angle bisectors QO and RO of base angles Q and R and wrote a slogan . prove that angle QOR=90 degree+1/2angleP. what is the benefit of these types of rallies?

Answer 1

Proof of  ∠QOR = 90° + ∠P/2

As PQR is a Δ,  ∠P + ∠Q + ∠R = 180°.
So   ∠Q + ∠R = 180° - ∠P
        (∠Q + ∠R)/2 = 90° - ∠P/2        ---- (1)

In ΔQOR, ∠OQR + ∠ORQ + ∠QOR = 180°
                 ∠Q /2 + ∠ R/2  + ∠QOR = 180°
Substituting from (1):  90 - ∠P/2 + ∠QOR = 180°
                               ∠QOR   = 90° + P/2  

   Writing mathematical and simple equations on placards is to attract the attention of the public in a new way.  Also it means to attract children and students towards the slogan "Save Girl Child, Save Future".
  
   Further, it also means that girls can do maths also and should do too.  The triangle is a symbol for the family.  Wide at one vertex, Husband at one vertex and the children at the third vertex.

   A girl or women is symbolized by the triangle. One part is herself.  The other part is the future of mankind. Because it is the girl who will give birth to future men and women.  So if girls are killed in the womb itself (foeticide) then the future of the human race will be in trouble. 

See the diagram too.

Answer 2

"The way you want to be treated . Do treat them as that way , save your sister whose going to help and care as mother."


A girl is the one who plays many roles in our lives. She is our mother, our sister ,our wife, our grandmother and many more . She is the cause of life,  because of her we are in this world . Before a sister, a mother, a wife, she is a girl and if you are saving a girl you are saving your world. This world of Homo Sapiens is just because of her. She is not your demand but she is your need .



These days no field is left where women haven't achieved success .She is flying high day by day . She has done all those works which appear to be impossible for men too. The woman in India touching the seventh sky these days. Sakshi Malik, Avani Chaturvedi, Indira Gandhi ,Sarojini Naidu, Anna Malhotra, Kiran Bedi are a few examples. These all examples proved that girl is not week this is our society which is trying to show her weak.



India is a country where women are worshipped as a good as and the same country has highest crime rate done against women. Some of the crimes of sexual harresment rape murder Dowry etc.



The society it may be because of the superstitions in our society. But this must be stopped. Government should increase more policies to stop this.



The girl is being killed in the womb of her mother without any mistake.



There is no mistake of that girl. It is just mistake in our mentality.
