Question

i need some answers checked

Answer 1

@Vocaloid

Answer 2

@Vocaloid hello?

Answer 3

this one is actually true (if the diagonals bisect in a quadrilateral then it must be a parallelogram)

Answer 4

not quite

since <A and <C are opposites they are congruent

5x - 1= x + 7 solve for x

Answer 5

2

Answer 6

notice how they are, again, opposite angles.

135 = 4x - 10

Answer 7

36.25?

Answer 8

good

Answer 9

a quadrilateral with 4 right angles, by definition, is a rectangle which is a parallelogram

so true

Answer 10

the diagram is somewhat unclear to me

however it seems like 5y - 10 = 2y

Answer 11

3.3^-

Answer 12

good but the answers are in fractions so 10/3

Answer 13

not quite

opposite sides have to be congruent

notice how adjacent sides are congruent in this picture

Answer 14

since opposite sides are not congruent then by definition this is not a parallelogram.

Answer 15

remember that opposite sides of a parallelogram are equal.

therefore

2x - 5 = x + 8
4y = 16

solve for x & y

Answer 16

good

Answer 17

good

Answer 18

not quite

for that to be true the sides have to be ~congruent~ AND ~parallel~

the question only states congruency so this is false

Answer 19

hi - what is your opinion about above posted - what choice my be true ?

Answer 20

than i see it clearly you marked it in left column the top- yes ? so than this is the right answer sure

Answer 21

ok. ?

Answer 22

sorry the right column on the top

Answer 23

a square is allways rhombus and rectangle

Answer 24

ok. ?

Answer 25

I believe that last one is correct. But let me pull up some stuff on how to classify quadrilaterals, just to make sure.

Answer 26

It appears to be so. See here
