If  abcd  is a parallelogram, what can we say about the diagonals  bd  and  ac?           a.  they're congruent to sides  ab  and  dcb.  they're congruent to sides  ad  and  bcc.  they bisect each otherd.  they're congruent

A parallelogram is a quadrilateral with two pair of parallel sides. The opposite sides of parallelogram are in equal length and opposite angles are of equal measure.

ABCD is a parallelogram with sides as AB, BC, CD and AD. BD and AC are the diagonals of the given parallelogram.

In parallelogram opposite sides are equal that is AB=CD, AD=BC

opposite angles are equal ,

Diagonals of parallelogram bisect each other.

Diagonals of parallelogram BD and AC are not congruent to the sides AB , CD and AD , BC.

Diagonals are not congruent.

Diagonals always bisect each other.

Option C is correct.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
