Question

help?

Answer 1

just guess :DDD

Answer 2

i know all the answers I just need to explain why?

Answer 3

31. trapezoid

32. rectangle

33. rhombus

Answer 4

this seems to take time.... for the 32 in a quadrilateral if it's a rectangle then
The two diagonals are congruent (same length).
Each diagonal bisects the other. In other words, the point where the diagonals intersect (cross), divides each diagonal into two equal parts

so... the 32 is a rectangle

Answer 5

for the 31...
when 2 sides r parallel in a quadrilateral..
it could be a parallelogram or a trapezoid .. but if it's a parallelogram.... angle CBD should equal to ADB ( alternate angles) since all sides r parallel each other...

but the data says that those 2 angles r not equal to each other...

so it's a trapezoid

Answer 6

for the 33

the say the ab is congruent to dc and ad is congruent to bc ... so this one is a parallelogram
since in a quadrilateral if 2 opposite sides r equal then it's a parallelogram
then it could be a rhombus or a rectangle.. we can't consider it as a square ( if it's a square then all sides should be equal)
but the diagonals become perpendicular to each other only in rhombus...

so this one is a rhombus...

hope this will help ya ...!! ( am srry i suck at explaining things clearly :()
