Explain why a rotation of 90 degrees around any point zero never maps a line to a line parallel to itself

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

What is the result of adding the system of equations? 2x+y=4 3x-y=6

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