Question

The shape below is a equilateral triangle. A) Does the shape have rotational symmetry? If so, identify the angle of rotation B) does the shape tessellate?

Answer 1

here is the pic..

Answer 2

@DaWizjr

Answer 3

what do you think rotational symmetry is?
& what does it mean for a shape to tessellate?

(this question is mostly about knowing definitions)

Answer 4

A shape has Rotational Symmetry when it still looks the same after a rotation (of less than one full turn).

Answer 5

@adamaero

Answer 6

what do you think happens then if you turn an equal sided triangle half or maybe a third of the way around?

Answer 7

it will look like this.

Answer 8

idk

Answer 9

whats the answer

Answer 10

I never even heard of this stuff so I can't help. sorry

Answer 11

@Xnlovely

Answer 12

if you turn it one more time, it will be back to the original position on the page

@becca1

Answer 15

so for A= yes it does still have rotational symmetry

Answer 16

"shape has Rotational Symmetry when it still looks the same after a rotation (of less than one full turn)"

so does it look the same after rotating less than one full turn?
examples of rotational symmetry are a circle (complete symmetry) or a square

Answer 17

yes it does so now, identify the angle of rotation

Answer 18

Answer 19

an equilateral triangle does not
you NEED to rotate it back to its original position (which means it's not rotationally symmetrical)

Answer 21

oh

Answer 22

B) does the shape tessellate?

Answer 23

tessellate is a cover (a plane surface) by repeated use of a single shape, without gaps or overlapping.

Answer 24

i think it does

Answer 25

i thought it does too but he made a point

Answer 26

ok

Answer 27

tessellate is a cover (a plane surface) by repeated use of a single shape, without gaps or overlapping.

Answer 28

@jadareese

Answer 29

i just need part B now

Answer 30

i say yes for b

Answer 31

why

Answer 32

for part b- yes they tesselate because they are able to fit together to make a pattern.

Answer 33

And they fit together in the pattern.

Answer 34

thank you so much
