The diagram below shows parallelogram ABCD with diagonals AC and BD intersecting at E What additional Information is sufficient to prove that parallelogram ABCD is also a rhombus?

9514 1404 393

  D.  AC ⊥ BD

Step-by-step explanation:

Given that  ABCD is a parallelogram, we already know A (BD bisects AC) and B (AB ║ CD). Statement C (AC ≅ BD) will not be true for a parallelogram or rhombus.

Statement D (AC ⊥ BD) guarantees the parallelogram is a rhombus.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
