1 Warm Up Use the coordinate plane provided to answer each question. 1. Plot points A (, ) and B (, ).. Is the distance between points A and B considered a horizontal distance, a vertical distance, or a diagonal distance? Eplain our reasoning. 3. How do ou calculate the distance between points A and B?. What is the distance between points A and B? 1 5. How do the negative coordinates affect the distance between points A and B? 1 Carnegie Learning 1.1 Translating and Constructing Line Segments 51C

2 Check for Students Understanding Use the given sides in each question. P Q R P 1. Construct a segment twice the length of segment PQ.. Construct triangle PQR. 3. Do ou suppose everone in our class constructed the same triangle? Eplain our reasoning.. Your classmate was absent from school toda and she is on the phone asking ou how to duplicate a line segment. What will ou tell her? 1 1 Carnegie Learning 1.1 Translating and Constructing Line Segments A

3 5. Use the coordinate plane provided to answer each question. One unit represents one kilometer. Vita s house is located at point A (9, 7). Her dog wandered awa from home, but fortunatel, the dog was wearing an identification tag which included Vita s phone number. Vita received a phone call that the dog was last seen at a location described b point B (7, 9). How far did the dog wander from its home? 1 1 Carnegie Learning B Chapter 1 Geometr on the Coordinate Plane
