The coordinates of a quadrilateral are (1, 2), (4,2), (1.4), and (4,4). After a transformation, the new coordinates are (1, -2), (4-2),
(1.-4), and (4,-4). Which transformation occurred?
(x, y) - (x + 2 y + 2)
dilation: (x + 2), (y + 2)
reflection across the y-axis

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
