Question

help me @nikato

Answer 1

i think its a rectangle

Answer 2

I think rhombus

Answer 3

i think rectnangle is correct

Answer 4

in order to be a rectangle then all right angles perpendicular at end
parallelogram is a rectangle out of shape
rhombus is a square out of shape

Answer 5

CANT be rhombus because the diagonlas wont always be congrunet.

Answer 6

square and rhombus lengths the same

Answer 7

the only proporty of the diagnolas of a rhombus is that they are perpendicular

Answer 8

because a property of the diagonals of a rectanlge is that they are congrunet.

and a square IS a special rectnangle

Answer 9

"A parallelogram is a rhombus if and only if its diagonals are perpendicular
A parallelogram is a rhombus if and only if each diagonal bisects a pair of opposite angles
A parallelogram is a rectangle if and only if its diagonals are congruent."

Answer 10

so its a rectangle?

Answer 11

^exactly
so according to our only given info "congruent diagonals"
the paraleelogram is a rectangle.

we dont know if the diagnolas bisect each otger or whether they are perpendicular

and yes. i believe its a rectangle

Answer 12

based on theorem 6.13
yes this would be a rectangle

Answer 13

the diagram looks like a rhombus, the diagonals still look perpendicular but the question states specifically that the diagonals are congruent therefore rectangle
