Mira made a game board from a piece of plywood. The board has four sides, with one pair of opposite sides parallel. The adjacent sides of the board are not congruent. Which statement about the board is true? A.) It is shaped as a trapezoid with adjacent angles which are congruent. B.) It is shaped as a parallelogram with adjacent angles which are congruent. C.) It is shaped as a trapezoid with two pairs of supplementary adjacent angles. D.) It is shaped as a parallelogram with two pairs of supplementary adjacent angles.
@zepp if it isnt to much to ask for can you check this one out for me to?
Ok, this must be a quadrilatere.. that's one
|dw:1336334568986:dw| With a pair of parallels.
Adjacent side aren't equal. That' means|dw:1336334598892:dw| Figures A & B doesn't not meet requirements A is a square and B is a lozenge
So our figure must be |dw:1336334701471:dw|
Parallelogram is not possible, because it has 2 pairs of parallels.
Now, we have A.) It is shaped as a trapezoid with adjacent angles which are congruent. and C.) It is shaped as a trapezoid with two pairs of supplementary adjacent angles. Let's draw A) |dw:1336334845861:dw| That would imply that this trapezoid is a rectangle, since adjacent angles are congruent, and a rectangle doesn't meet the requirements either.
C.) It is shaped as a trapezoid with two pairs of supplementary adjacent angles. Two? So two of them must be 90 degrees, since supplementary angles = x+y=180 |dw:1336334972832:dw|
It only has a pair of opposite side parallel; The adjacent sides of the figure are not congruent. Thus, statement C is true.
Wow thank you so much, you just saved my life lol
