Line segment PQ is shown on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment PQ is shown with Q as ordered pair negative 1, 3 and P as ordered pair negative 5, 3. The line segment is rotated 270 degrees counterclockwise about the origin to form P'Q'. Which statement describes P'Q'? P'Q' is two times the length of PQ. P'Q' is equal in length to PQ. P'Q' is half the length of PQ. P'Q' is parallel to PQ.
Do you think that a rotation would cause the length of the line segment to change?
not quite, because all you're doing is rotating that same line around a certain point, rotating it shouldn't change its length |dw:1444304668291:dw| if thats the line segment
all we're doing it is rotating it around the axes like so |dw:1444304746566:dw| so the length shouldnt change
so what can we say about the lengths of both these lines?
SO IS IT b
yupp thats correct!
