PLZ HELP Draw a non-square rectangle or parallelogram or an isosceles trapezoid in the coordinate

plane so that portions of the shape are in each of the four quadrants. Explain what would

happen to your shape if you transformed it using each of the given rules.

2. (-x, -y)

1. (x, y)

4. (x, y + 3)

3. (x - 4, y)

6. (4x, 4y)

5. (r - 1, y + 4)

8. (2x, y-1)

Step-by-step explanation:

Following changes will be there when the figure is transformed by the given rules.

1). Rule for transformation has been given as,

   (x, y) → (x, -y)

   Reflection across x axis.

2). (x, y) → (-x, -y)

   Rotation of 180° about the origin.

3). (x, y) → (x - 4, y)

   Shifted 4 units left horizontally.

4). (x, y) → (x, y + 3)

   Shifted vertically up by 3 units

5). (x, y) → (x - 1, y + 4)

   Shifted 1 units left horizontally and 4 units up vertically.

6). (x, y) → (4x, 4y)

   Dilated by 4 units.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
