give me a second, lol

Okay cx

how do you upload an image?

Attach File *I think*

thanks

sorry for the wait

number 31

|dw:1366882143016:dw|

nope, doesnt have to be congruent

lets start with D)

Well, if DAB = 40Âş, and DCB = 40Âş then ADC = ABC which makes it a parallelogram right?

i meant, not all 4 sides have to be congruent

why does

not necessarily

let me redraw that

a kite

|dw:1366882582720:dw|

peter, oh yes a kite does satisfy these conditions , but is not a parallelogram

are rhombuses (rhombii?) kites?

Can I post the solution? ;)

sam, i would prefer you not, but...

give loveyou a chance :)

Lets not give me a chance lol im making myself feel stupid

how about this: look at all the choices from D to A and try to draw a counterexample for each one.

peter, good idea :)

lol,letsnot, i didnt get sleep im too tired for this :P

no, let's do it!

Feel free

no! i'm volunteering you to do it! it's your problem...
I already know the answer.

It's not my problem lol

"Geometry Mathquestion for Loveya69"

thanks perl, I didn't remember that

and here http://www.wyzant.com/help/math/geometry/quadrilaterals/trapezoids_and_kites

peter I got B)

@perl in my opinion the answer would be option b and option d!!!!!

option d is wrong, because you can produce a kite , b is right

a kite satisfies option d and is not a parallelogram

no, in question it is given what conditions must be true for it to be a parallellogram

but what about angles of kite?????

|dw:1366929990059:dw|

|dw:1366930082573:dw|

in triangle abc, it is an isosceles triangle. it means that angle 1=angle2!!!! right @Peter14

sure, it could be a rhombus, and therefore a parallelogram, but you can't assume that.

@Peter14 for this time, please forgot the question, concerntrate on my question!!!!

angles 3 and (not given) could vary. the sum just has to be 280.

sure, let's go with your question. yes, angle 1 = angle 2 and angle 4= angle 5.

but in perl question!!!!!

|dw:1366885812169:dw|
so what about its angles?

angle 1=angle2 and angle4=angle 5

yes... and?

and what?

what exactly are you trying to prove here?

that adjacent angles are equal

|dw:1366886101425:dw|

its difficult to force this into a kite shape

(shrug) It doesn't really matter to me. I've already taken geometry.

for instance a square is a kite

it should say, a kite has at least one pair of congruent angles

about kites!
