Answer 1

Not necessarily.

Answer 2

What is given here is a rhombus, which may or may not have right angles.

Answer 3

then ABCD is a square....

Answer 4

i mean if AB=BC=CD=DA and angleB=90deg, then the figure is a square

Answer 5

True, but we are given only that the four sides are all the same length.

Answer 6

it also says angleB is a right angle.....

Answer 7

If any one angle of the rhombus is a right angle, then so are the other three. If one of the angles is not a right angle, then none of them is.

Answer 8

What this all boils down to is this:
all squares are rhombi, bue not all rhombi are squares.
