The blue triangle has rotated from quadrant i to quadrant iii about the origin. describe the effects of the rotation on the coordinates of the blue triangle. a) the coordinates switch positions. b) the signs of the coordinates change. c) the sign of the x-coordinate changes. d) the coordinates switch positions and the signs change.

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain

How does reflecting or rotating a figure change the interior angles of the figure?
