Question

trapezoid PQRS was rotated 60 degrees around a point. Which point could have been the center of this rotation? (picture provided in comments)

Answer 1

@aum do you know how?

Answer 2

When you have a center of rotation, it is like a center of a circle where any two points on the circle will be at the same distance from the center. Make a guess first. Let us say the guess is C. Then ask yourself is CQ = CQ'? Is CR = CR'? etc. If it is yes for all of it then it is the center of rotation. If not try some other point.

Answer 3

the options are a b c or d so i don't understand

Answer 4

Yeah. In my example above you can quickly rule out point C as the center of rotation because CR is not equal in length to CR'. CR is much shorter than CR' and so C is not the center of rotation.

Answer 5

Try other points: A, B and D and see which one is likely to be the center of rotation.

Answer 6

is it a?

Answer 7

because a and both of the s seem to be the same length..

Answer 8

nvm

Answer 9

b?

Answer 10

obviously s @glittergoddess

Answer 11

as its rotated by fixing s at its position and point along s is given as b so dat means b is ur answer @glittergoddess
