Isometries and Congruence
{"Image DocumentName": "Isometries and Congruence", "Image ImageDescription": "An isometry is a map that preserves distances. Thus f is an isometry if and only if. |f(P)f(Q)| = |PQ| Two sets of points (which define a triangle, angle, or some other figure) are congruent if there exists an isometry which maps one set to the other.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
