Understanding Scaled and Rotated Figures

The video tutorial explains how figure two is a scaled and rotated version of figure one. It guides viewers through identifying corresponding sides between the two figures, focusing on side EA in figure one and its counterpart in figure two. The tutorial uses a methodical approach to determine side correspondences, emphasizing the importance of recognizing longest sides and right angles. The conclusion highlights the key points and confirms the corresponding sides.

What transformation has been applied to figure two compared to figure one?

• It has been scaled down and rotated 180 degrees.

• It has been scaled up and rotated 90 degrees.

• It has been scaled up and rotated 180 degrees.

• It has been scaled down and rotated 90 degrees.
