circle
arrow

Answer 1

#1
Question looks incomplete, not sure what "polygon..." stands for what. Please complete question.
However, all <i>regular</i> polygons have rotational symmetry.

#2
Translation is just one way to tessellate. There are three other ways, reflection, rotation, and glide reflection (i.e. reflection followed by a translation, or vice versa).
You only have to find one shape that that tessellates, but not with translation alone to declare the statement false. (e.g. try a triangle).

#3 is not posted.

#4
a 180° rotation is obtained by the following operation:
R_180: (x,y)&rightarrow;(-x,-y).
For example, point (5,-2) rotated about the origin is (-5,2), and so on.

#5
Pentagram is a 5-sided star. Try to see if you can tessellate it.
There are many kinds of <i>regular</i> polygons, some can tessellate, and some cannot.
(To find out what is a regular polygon, see:
https://www.mathsisfun.com/geometry/regular-polygons.html
)
Regular polygons have internal angles equal to A=180(n-2)/n, where n is the number of sides.
The polygon can tessellate if A divides 360, i.e. fits around a point.
This means that 360/A must be a whole number to tessellate, or
360/(180(n-2)/n)
=2n/(n-2) must be a whole number.
This way, you can find all the regular polygons that can tesselate.
For example, for a triangle, n=3,
and 2*3/(3-2)=6 is a whole number, so a "regular triangle", or equiangular triangle can tesselate.
For an arrow, try to see if you can tessellate. I did not find a way to do that.

Answer 5

Mr.pickles is correct!

Answer 6

mr.pickles is correct 5/5

Answer 7

5. would be a pentagon

Answer 8

6. Yes, it does. As a Ferris wheel has a circular shape, it will have the same position every 45 degrees, because it has 8 cars. (1/8 of 360 = 45)

Answer 9

I got 100%. Mr Pickles is correct. But on question #6, put it into your own words.

Answer 10

Mr. Pickles [ amazing name ] is correct,

I got 100% for 2019

Answer 11

tysm mr pickles! I agree with anon mouse awesome name XP

Answer 12

Correct answers are:
1. A
2. False
3. D
4. A
5. B
6. A. When you rotate it 60 degrees (360/3), they look exactly like it did before because every corner is at 60 degrees.
B. Yes, because it doesn't overlap nor doea it have gaps, so there for they can be used on a flat roof and not leak.

Answer 13

Thank you Mr Pickles!

Answer 14

I believe wrong is right

Answer 17

Mr. Pickles is 100% correct! Thank you!

Answer 18

Mr.Pickles thank you I got 100%

Answer 19

thx everyone i got 100%

Answer 20

OMG THANK YOU SO MUCH MS PICKLES I GO A 100%

Answer 21

@Mrpickles i'm confused on question 6. can you explain PLEASE!!!!

Answer 22

Um so on question six your saying that everywhere it turns it is 45 degrees yes also look at my name →

Answer 23

THX SOOOOO MUCH Mr Pickles and Tessa Quinn

Answer 24

@Mr Pickles


Is right!

Answer 25

5/5 thanks!

Answer 26

Here is what I put for answer 6 (Yes the Ferris wheel does have rotational symmetry because it`s center of rotation is exactly 90 degrees a regular octagon is closed figure with completely even sides) this answer will give you 100 percent on your quiz just in case though put some of it in your own words because other kids might just use the whole answer without changing it if you do the same they might think you cheated

Answer 27

Sorry forgot to change my username I was the Angel of God kid

Answer 28

MR pickles is still right 5/5 thanks so much!!

Answer 29

Thank you Mr Pickles

Answer 30

Thanks Mr.Pickles

Answer 31

These are the real answers 2022!
1. A
2. C
3. D
4. A
5. B
6. The answer is yes, but do NOT copy me for the writing answer. This is what I put:
Yes, it does have a rotational symmetry because it has 8 equal lengths of sides, so when it rotates it stays the same length as before over and over again, forever and ever.

Answer 32

still correct

Answer 33

I think for the last question they give everyone different shapes, as mine is not what everyone said theirs was but I had the same questions, and some said theirs was a circle, others said theirs had how many different points and stuff, so I believe they gave everyone different shapes on the last question.

Answer 34

1. The diamond or A
2. yes; 72°
3. Q
F O

F R


O O R
4. (–3, 5)
5. The one that looks like a rectangle
6. yes, because it has 8 even sides so it could spin over and over again and still be the same.

Have an amazing day!
