To get your triangle in Quadrant 4, you could have just reflected the triangle over the x-axis the first time. This would only require a single transformation instead of 3.
The result would be the same.
Answer: 277 units^2
Step-by-step explanation:
Answer:
sometimes true
Step-by-step explanation:
if x is a positive integer the statement is true, if x is negative integer the statement will be false.
Answer:
396 Square feet
Step-by-step explanation:
1.) First find the side closest to you. 6 x 12 = 72. Then double it to match the parallel side. 72 x 2 = 144
2. Find the side to the right and left, 7 x 6 = 42. Then double it to match the parallel side. 42 x 2 =84
3.) Find the top side and bottom side. 12 x 7 = 84. Then double it to match the parallel side. 84 x 2 = 168
4.) Find the total surface area. 144+84+168=
5.) The total surface area is 396 square feet

Use property that the diagonals of a parallelogram bisect each other, =>
x+y=18
y+(can't read)=22
Solve for x and y.
#18
z+60=180 [angles on a line are supplementary]
x=z [opposite angles of a parallelogram are congruent]
y=50 [alternate interior angles between parallel lines AD and BC]
#19
3v=30 [ opposite sides of a parallelogram are congruent ]
solve for v.
2u-1=19 [ ditto ]
solve for u.
#20
(a) AB//DC [ adjacent angles are supplementary ]
(b) PS//QR [ ditto ]
#21
1) a parallelogram with one angle 90 means the adjacent angles are 180-90=90. This in turn means all angles are 90, so the figure is a rectangle (adjacent sides may or may not be equal in a parallelogram).
2) a rectangle with adjacent sides equal must be a square.
