Question

The grid shows figure Q and its image figure Q' after a transformation:

Figure Q is a pentagon drawn on a 4 quadrant grid with vertices at 2, 4 and 4, 2 and 5, 4 and 7, 5 and 3, 7. Figure Q prime is a pentagon drawn with vertices at 4, negative 2 and 2, negative 4 and 4, negative 5 and 5, negative 7 and 7, negative 3.

Which transformation was applied on figure Q?

Counterclockwise rotation of 90° about the origin
Clockwise rotation of 180° about the origin
Counterclockwise rotation of 270° about the origin
Clockwise rotation of 270° about the origin

Answer 1

okay so since the points are mirror opposites what do you think the most logical answer is?

Answer 2

a or c not sure

Answer 3

@maddisonGruby

Answer 4

okay, have you tried plotting them on a graph?

Answer 5

no. @maddisonGruby

Answer 6

is either a or c rihgt?

Answer 7

okay well here look at my graph. then pic either a or c, because one of those is correct

Answer 8

a @maddisonGruby

Answer 9

counter clockwise by 90 degrees means your going into the fourth Quadrant, you need to go to the second

Answer 10

so c?

Answer 11

yep, i was just drawing a graph to show you but you got it

Answer 12

okay could you help with 1 mor eples @maddisonGruby

Answer 13

totes shoot it

Answer 14

ok

Answer 15

Figure EFGH on the grid below represents a trapezoidal plate at its starting position on a rotating surface:

A trapezoid EFGH drawn on a 4 quadrant coordinate grid with vertices at E negative 4, 8. F is at negative 7, 5. G is at negative 4, 3. H is at negative 2, 5.

The plate is rotated 90° about the origin in the counterclockwise direction. In the rotated trapezoid, what are the coordinates of the endpoints of the side congruent to side EH?

(8, 4) and (5, 2)
(4, −8) and (2, −5)
(−8, −4) and (−5, −2)
(−8, −4) and (−5, −7)

Answer 16

okay so by rotating 90 degrees counter clockwise we are going into the 3rd quadrant, meaning all of our points will be two negatives meaning we can eliminate a and b

Answer 17

ok

Answer 18

@maddisonGruby i think its d but not sur e

Answer 19

take a look at this to help

Answer 20

its not helping

Answer 21

its confsuign me

Answer 22

i believe that c is the correct answer because if to were to rotate the figure EH would be close to the x Axis

Answer 23

ok

Answer 24

ae you sure? @maddisonGruby ill tell u uf i ge the ones wring that u hlped me wiht.

Answer 25

im positive that its c
