1. Which of these transformations are isometries? The diagrams are not drawn to scale.
*two pictures*
(I) parallelogram EFGH → parallelogram XWVU
*two different pictures*
(II) hexagon CDEFGH → hexagon TUVWXY
*two more different pictures*
A. I only
B. II and III only
C. I and III only
D. (0 pts) I, II, and III
Sherk is NOT right. I’m guessing conexxus answers is wrong too. Oh goodness I’m failing math but hopefully I’ll help others by telling them to NOT trust them(: <3
1. My question version EFGH XWVU CDEFGH YXWVUT EFG VWU
Answer: I,II, and III
2. My question version Which image is the translation of ABC given by the translation rule (x,y)->(×-2,y+2) C the dashed line triangle is on the top left
3. My question version Which translation rule describes the translation that is 6 units to the left and 5 units down? B (×,y) ->(×-6,y-5)
4. If point P(4,11) is reflected across the line y=3, what are the coordinates of it's reflection image? D (4, -5)
5. The vertices of a triangle are P(-4,1), Q (-2,-8), and R(8,-1). What are the vertices of the image reflected across the y-axis? C P'(4,1), Q' (2,-8), and R'(-8,-1)
6. D the triangles should look mirrored horizontally
7. The hexagon GIKMPR is regular. The dashed line segments form 30 angles. what is the image of ON after a rotation of 180? B OH
8. What is the angle of rotation about O that maps PQ to GH? A 240
9. How many lines does the figure have? D 6 it's a hexagon
10. Which letter has rotational symmetry? A I
11. Reflectional, rotational, and point symmetry? D it's a circle
12. The shape shown above has Which type of symmetry? B point symmetry only it looks like the Ying yang ☯️ symbol
13. C (11,2)
The last two are easy. Each person's test is different which is why I wrote out the whole question on most of them. Hope this helps!
Alright guys I’m gonna take one for the team I’ll tell you if ones right. Brb
"Regal" i got 2, 7,8,9,13 wrong
none of these people are correct
Guys none of them are correct go somewhere else done fail like me good luck🙏🙏
So who is right????
clearly the test is randomized each time, dont trust just letter answers, but you can use "Who"s answers in order to match the questions up with your test and get a few right.
Oop thank u, Ima go figure this out
Use wisely if you want me to show you that i got all of the right then put you ig so in can send you a picture of my answer
O
bruh i fr got a 6/13 thanks alot......
tried gathering it from other places got only half where right
4) (6,-5)
8) 300
9) 1
10) H
11) circle
12) no symmetry
13) (1,10)
if 14 and 15 do well i pass if not i fail and i dont know the others
Happy to help from connexus is wrong I got a 5/13 here are the correct answers
1- II and III only
2- Figure D
3- (x,y) -> (x-6, y-5)
4- (3,-8)
5- P'(-4,1), Q'(-2,8), and R'(8,-1)
6- Figure A
7- ON
8- 240*
9- 5
10- I
11- Figure B
12- point and line symmetry
13- (1,10)
14 (essay question)- When the image of D is reflected across the line "L", it will appear backward, placing its curved side first and then its straight back line. When it's reflected again on line "m", it will return back to its original orientation or shape in beginning, with the straight back line first and the curved side second.
15 (essay question)- The flags are a translation of each other, moving only a few coordinate points ahead but NOT changing their orientation or direction. In a rotation image, the image WILL change the orientation it's held at and move the points left or right prior to their setting. In simple terms, a translation only moves the location of an image (which is true for this image), while a rotation will change its shape and rotate it into a new position.

All the answer are for geom B transformations unit test part 1 and I got a 100%
1. I and III only (its not I, II and III)
2. Its a graph but its the one where the second triangle is to the bottom right
3. (x-6, y+5)
4. 6, -5
5. P(-4,1) Q(-2,-8) and R(8,1)
6. Also a graph but its the one where the reflection is vertical, it goes over the x axis not the y (not the one where they are on opposite corners the other one)
7. OH
8. 240 (not 120 go CCW)
9. 3
10. S
11. The circle!
12. Point and line symmetry
13. 5,9
14. Look up the question for this one someone answers it on a different forum along with 15.

14. When D is reflected across line L it will be mirrored backward, curve side first then the straight line. When it is reflected again on line m it is returned to its original placement.
15. The flag placed below the horizontal axis is the sown ward translation of the flag that is over the same axis.
