A triangle is rotated 35 degrees about the origin. What is true about the relationship between the image and the pre-image?
A) The lengths of the sides and the measures of angles are preserved, so the triangles are congruent. <--- * This one?
B) The lengths of the sides are enlarged and measures of the angles are preserved so the triangles are similar.
C) The lengths of the sides change and the measures of the angles change as well, so the triangles look nothing alike.
The lengths of the sides are reduced and measures of the angles are preserved, so one triangle is a reduction of the other.

1. A triangle is rotated 35° about the origin. What is true about the relationship between the image and the pre-image?
A, The lengths of the sides and the measures of the angles are preserved, so the triangles are congruent.
2. Which of the following are the coordinates of point F', the image of point F, after a rotation of 90° about the origin?
B, (-3, 0)
3. The coordinates of PRS are P(-3, 2) , R(2, 5) , and S(0, 0). Which of the following could be P'R'S' after a 270° rotation?
B
4. A segment with endpoints X(-6, 2) and Y(-1, -3) is rotated 90° about the origin. What are the coordinates of X' and Y'?
C, X'(-2, -6) and Y'(3, -1)
5. What is the angle of rotation about C that maps the solid figure to the dashed figure?
C, 270°
6. A segment with endpoints A(3, 1) and B(-1, -1) is rotated 90° about the origin. What are the coordinates of A' and B'?
B, A'(-1, 3) and B'(1, -1)

10. A Ferris Wheel is drawn on a coordinate plane so that the first car is located at the point (30, 0). What are the coordinates of the first car after a rotation of 270° about the origin?
C, (0, -30)
I got 10/10 on Kit's answers he is correct
liliy is also only 5/10
Kit is 100% correct
Kitts is 100% trust me I was scared to but I did it and it was right lol

kit is 100% right idk what that one chick is talking about a "5/10" trust kit
I just did Aaureliax~'s and it worked great if your doing this on pearsonconnex then I did the rotations practice on 5.3.4 unit 5 transformations I got 100% updated 5/12/2021
Aaureliax 100% correct
Aaureliax right got 100%
Aaureliax is right, got a 10/10!
Aaureliax is ken
Yeah, both Aureliax and Kit worked for me. I think issues arise from the differing answers in honors' geometry
who is correct for conections acedamy
I got a 100% from kit
Kit is still right, 2022
Aureliax is the safest bet for answers since you see the answer choices and not just the letters. Since some programs will have them switched around
Kit's is still correct
I'm stuck on this too
Kit is still right 2022
oof is right for anybody with the U4L3 rotations practice.
i used kits answers and only got a 50 too :( idky
these ARE CORRECT. JUST SUBMITTED AND GOT ANSWERS. This is for rotations practice
