Which set of statements would describe a parallelogram that can always be classified as a rhombus? I. Diagonals are perpendicular bisectors of each other. II. Diagonals bisect the angles from which they are drawn. III. Diagonals form four congruent isosceles right triangles. 1. I and II 2. I and III 3. II and III 4. I, II, and III

1. I, II,

Step-by-step explanation:

I. Diagonals are perpendicular bisectors of each other  

Yes, because 4 sides are congruent so it makes the two diagonals perpendicular bisectors

II. Diagonals bisect the angles from which they are drawn

Yes, That is the property of the diagonal!

III. Diagonals form four congruent isosceles right triangles.

No, only two pairs of right triangles are congruent and sometime the side of each pair are different to each other.

Hence, we choose I and II

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
