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!
