Question

Sunita performed a transformation on trapezoid LMNQ to create L′M′N′Q′ as shown in the figure below.
What transformation did Sunita perform to create L′M′N′Q′?

Answer 1

plz help

Answer 2

PLZ HELP

Answer 3

plz plz plz help

Answer 4

Notice how L is (-7,-2) and it turns into L' (-2,7)

In general, if you have (x,y) and it turns into (y,-x), then you have a 90 degree clockwise rotation about the origin (0,0)

So you're rotating the entire figure 90 degrees clockwise

Answer 5

otation of 90 degrees counterclockwise about the origin

rotation of 270 degrees counterclockwise about the origin

reflection across the x-axis

reflection across the line of symmetry of the figure

Answer 6

well if you rotate something 90 degrees CW, then that's the same as rotating it 270 degrees CCW

Answer 7

so it will be A

Answer 8

B

Answer 9

I think it is B

Answer 10

it is B

Answer 11

K can you plz plz plz help me with one more??

Answer 12

ABCDEF is congruent to PQRSTU in the figure below. They represent the bases of two fountains.
If the total length of the brick edge for each fountain is 110 feet, what is the length of side UP?

Answer 13

You are a genius thanks for helping on the first one

Answer 14

Hint: the polygons are congruent, so by CPCTC,

UP = AF

So your first task is to find AF. You can do this by letting x = AF and noticing that

x + 15 + 18 + 22 + 22 + 18 = 110 (since the perimeter of each polygon is 110)

Solve that for x to find AF. This will be your answer for UP as well

Answer 15

X=15?
