<span>We have to describe two ways of drawing the square from the shadded figure: 1. Reflect the figure ( triangle ) across the x-axis, after that rotate it around the origin 90 degrees clockwise and than reflect over the y-axis. 2 . Rotate the figure around the origin 90 degrees clockwise. Then reflect across y-axis. Finally, rotate it around the origin 90 degrees counterclockwise. </span>
When a line segment is bisected into 2 halves, the two halves are equal. In this case, when AB is bisected by CD, AE and BE would be equal and each point on CD should be equidistant from point A and point B. Therefore, AC = AB.
