Unit 3, Lesson 16# Symmetry in the Coordinate Plane

EngageNY 45 min(s)

Students understand that two numbers are said to differ only by signs if they are opposites of each other. Students recognize that when two ordered pairs differ only by the sign of one or both of the coordinates, then the locations of the points are related by reflections across one or both axes. Give an example of two opposite numbers, and describe where the numbers lie on the number line. Students locate and label points whose ordered pairs differ only by the sign of one or both coordinates.
