Yes it is really hard to say what is 1+1 ! this is a very popular trick too ive seen mostly people doing!They say what is 1+1 and if the person answers 2 , then they say no its 11 and if the person answers 11 then they say its 2!lol! thats really funny!

but here we are doing proper Maths so 1 + 1 =2  ANSWER

CPhill i think urs and mine are both the same!becoz ive written also what u have said !opposite angles are equal!

Sorry CPhill i didnt see ur post while making mine!im just reading it!

jboy , thank you very much for your help!i still have some doubts but!umm!i couldnt understand properly how u found out CDB . i was thinking that as DBC is 60 then in a parallelogram opposite angles are congruent so why cant CDB also be 60 becoz it is also opposite!i have made the figure lots of time and have made one just now too and so the figure made me think this!

Is the figure made above correct!im not good at making such kinda things so i dont know what ull think about this!BTW on ∠CDB ive written 60 becoz i think its that as opposite angles are congruent!so what do u think about it!If you can then can u please explain me a lil further , maybe with ur diagram !

Yes!that helps lots!i never thought of it that way,thanks for this new easy way ill always remeber it!Its a great help for not losing marks becoz of some silly mistakes!Thanks for it!

Thumbs up with points from me CPhill!Thank you very much!

OOOHHH!NOOO! 

What a SILLY ,mistake i made!

i thought the perimeter would be lxb instead of 2(l+b)!i thought hard but still the answer in my mind came lxb!Oh no what did i do!why do i always get confused in the perimeter and area of a rectangle! Now i have lost two marks , thats soo sad!is there any way to remember them both corectly CPhill?

Now i'll never make such a mistake!

BTW thank you for the answer!thumbs up from me!

Melody the reason i gave you was just an example of someother reasons!so is there any other formula we can use to find out using other reasons !

i knew that melody about what you were referring to ! its just that i couldnt say or mistakenly didnt say it to Zegroes in proper words but still girls of my age or aroung or smaller than my age dont call the other girls beautiful,whether its inner beauty or outer beauty,and you know why (becoz they just like to call themselves beautiful!) !

i am happy you liked my poem , actually i was a little nervous about writing it and showing to you all becoz i thought what if no one likes it!but i'm happy you liked it!

thank you very much !And a thumbs with 5 points  from me for your beautiful words!

oh!Thanks for them CPhill!I can use them at school!only if the teacher doesnt take 'em away!

But thanks for the points too!
