if wxyz is a parallelogram which of the following statements must be true A angle w is supplementary to angle y B angle w is congruent to y C wxyz is a parallelogram D wxyz is a trapezoid E angle w is a right angle F wx is perpendicular to xy
i need help

Opposite sides & opposite angles of a parallelogram are concurrent Adjacent angles of a parallelogram are supplementary.
And one more thing a parallelogram is itself a special type of quadrilateral therefore it can't be any other quadrilateral such as trapezoid or rhombus etc. ok!
Angles of a ||gm aren't right angles 2 obtuse & 2 acute so the lines of ||gm aren't perpendicular too.
so are the answers a,b, and c
no; only B & C are answers "A" won't be the answer becoz opposite angles are only congruent not supplementary. but remember adjacent angles same as angle "W" & "X" will be supplementary.
the answer was wrong thanks for your help though
wt do u mean wt are the answers?
the quiz i was taking said it was a,b,c,e,f
May be ur quiz has considered square & rectangle also as a parallelogram so the answers are abcef but considering parallelogram in a strict way; i mean take ||gm as a special quadrilateral then u will get only b & c as answers take a look @ this http://www.coolmath.com/reference/parallelograms.html
