Question

Perform the following transformations. You can either graph the shape or record the coordinates on the table.OriginalNewA(0,0)B(4,1)C(5,-2)OriginalNewA(2,1)B(1,4)C(4,3)

Answer 1

If a point with coordiantes (x, y) is reflected across the x axis, the sign of the x coordinate would remain the same while the sign of the y coordinate would be reversed. It becomes (x, - y)

Given the original coordinates A(0,0), B(4,1), C(5,-2), if we reflect across the x axis, the new coordinates would be

A'(0, 0)

B'(4, - 1)

C'(5, - - 2) = (5, 2)

Also, if a point with coordinates, (x, y) is rotated 90 degrees clockwise about the origin, the new coordinates would be (y, - x). Thus, if the original coordinates A(2,1), B(1,4), C(4,3) are rotated 90 degrees clockwise, the new coordinates would be

A'(1, - 2)

B'(4, - 1)

C'(3, - 4)
