Our example may sound a bit silly, but in geometry we use transformations all the time to bring two objects near each other, turn them to face the same way, and, if necessary, flip them to see if they are similar. George E. m∠ A 5 47. How did what you learned today help you answer the HOW can you determine congruence and similarity? Course 3, Lesson 7-1 Geometry 14. So, there is a sequence of rigid motions (which are also similarity transformations) that maps one to the other. This is a proof of the statement “If a line is parallel to one side of a triangle and intersecrts the other two sides at distinct points, then it seperates these sides Similarity transformations include reflections, translations, rotations, and dilations. Lesson 1 and 2 Skills Practice Translations and Reflections on the Coordinate Plane For Exercises 1 and 2, use the coordinate plane below. • Cross ratios of lengths.
