Please help... im stuck! @abram134 @Angel_Bear19 @amysparkly12 @blurbendy @blurbendy @Bpgrace @Bush993 @Coolsector @Catlover5925 @CausticSyndicalist @Crissy15

Answer 2

@Directrix

Answer 3

Compute the slopes of the diagonals WY and ZX.

Slopes of perpendicular lines have a product of -1.

So, see if the slopes you get multiply to -1.

If so, the diagonals are perpendicular.

Answer 4

Alright.. Got that

Answer 5

Uhh.. is that it?

Answer 6

good job @Directrix

Answer 15

umm i might know

Answer 16

:)

Answer 17

da smiley face tho lol

Answer 18

the vertices are:
A(x , 0), B (0 , y), C (-x , 0) , D (0 , -y)
AB = BC = CD = AD = √(x^2 + y^2)
diagonals AC on x-axis and BD on y-axis intersecting at origin must be perpendicular.

Answer 19

So would that be the proof?

Answer 20

Yes

Answer 21

yea

Answer 22

Okay, on my side it's showing a lot of questions marks so idk if there is something missing
