AO= 5x+2 BO= x-1 CO=3x-7 DO= 3x+8 Quadrilateral ABCD is a parallelogram if it's diagonal bisect each other. Prove that quadrilateral parallelogram by finding the value of x.
do you can post an image about this parallelogram ?
do you know the properties of a parallelogram ? how are the opposite angles and sides ?
Yes but I don't study
Come on
@AZ
HELP!!!
I'm finna cry
the diagonales bisect each other - what mean this ? how you can write this using the given details ?
Add up to 180
no look please on this image how are OB and OC or OA and OD ?
signed on this image
Divide by 2
no yes the diagonales bisect each other
from this result OA = OD and OB = OC
90 divided by 2
rewrite these equalities using these given expressions
They equal to each other
\(\color{#0cbb34}{\text{Originally Posted by}}\) @Shaypop 90 divided by 2 \(\color{#0cbb34}{\text{End of Quote}}\) you dont work now with angles
\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 from this result OA = OD and OB = OC \(\color{#0cbb34}{\text{End of Quote}}\) using these given expressions rewrite these equalities
5x+2=3x+2
OA=OD 5x +2 = 3x +8
3
what is this 3 ?
The answer
do you think x = 3 ?
No
why no ? you need find the x value and prove that diagonales bisect each other
It is b
what is this b ? i dont see there given any choices for x value
x = ?
\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 OA=OD 5x +2 = 3x +8 \(\color{#0cbb34}{\text{End of Quote}}\) use this to calcule x = ?
It's 3
so x = 3 then now can you prove that the diagonales bisect each other ?
\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 OA=OD 5x +2 = 3x +8 \(\color{#0cbb34}{\text{End of Quote}}\) use this
substitute in place of x the 3
I did
and what you get ?
2,2 and 17,17
so what mean this ? what result from these ?
I plug it in
written in this way 2 = 2 17 = 17
Ok
\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 written in this way 2 = 2 17 = 17 \(\color{#0cbb34}{\text{End of Quote}}\) from these result that the diagonales bisect each other so result that ABCD is a parallelogram ok ?
questions ?
