WILL GIVE MEDAL!!!


1. Which of the following is true about the shape?

picture link down below

It does not have rotational symmetry.

It has rotational symmetry of order 2.

It has rotational symmetry of order 4.

It has rotational symmetry of order 8.



2. Quadrilateral A B C D has vertices at A negative two comma negative one, B negative four comma negative seven, C negative nine comma negative three and D negative eight comma negative six. It is reflected across the x-axis. What are the new coordinates? Explain.

Answer 2

please help @Hamoody1996

Answer 3

the picture wont open ;(

Answer 4

sorry ...@Hamoody1996 its resembles the sun... its a circle with 8 triangles around it evenly spaced and same size

Answer 5

Answer 6

@Hamoody1996

Answer 7

i dont know what that means pls help...@Hamoody1996

could you at leasy help with the 2nd one pls pls pls

Answer 8

2
The rule for reflecting over the x-axis is (x,y) changes to (x,-y)

A(-2,1)
B(-4,7)
C(-9,3)
D(-8,6)

Answer 9

thanks @tylorherpeche can you also explain it to me so i know how to do it next time

and @Hamoody1996 i got number 1 already

Answer 10

ok ;)

Answer 11

gtg ttyl :)

Answer 12

wait pls explain @tylorherpeche

Answer 13

how to do it @tylorherpeche

Answer 14

For all the vertices, the sign of y-coordinate changes. For example, A(-2,-1) will be A'(-2,1) after reflection in x-axis. B(-4,-7) will be B'(-4,7) C(-9,-3) will be C'(-9,3) D(-8,-6) will be D'(-8,6) Reflection does not change the shape or size of the figure. It just flips it over.
now i really got to go

Answer 15

THANKS!!
