Translations Introduction

What is an Image? Watch the video and notice the types of transformations. What's an IMAGE? Vocabulary Matching These are words from the first video transformation any change to an original item image the item after it has been changed in some way translation a move either horizontally or vertically rotation a change by turning a figure a certain number of degrees reflection a change that is like a "mirror image" dilation a change in size that involves a scale factor What Properties of a Figure Stay the Same After a Translation? Watch the video and jot down notes. Be ready to answer the questions below. Transormations: What changes? What stays the same? What do you call the "IMAGE" of the original figure? Tall short prime Same vs. Different Stays the Same angle measurment area perimeter Different location How Do You Use Coordinates to Translate a Figure Horizontally? Watch the video and take a few notes. Use them to answer the following questions. Horizontal Moves If you translate a figure HORIZONTALLY, what happens to the x-coordinate? it stays the same it changes by addition it flips If you translate a figure by moving HORIZONTALLY, what happens to the y-coordinate? it changes absolutely nothing it flips If you translated the point A(2, 6) by moving RIGHT 3 (x+3, y) what is the ordered pair for A' ("A Prime")? A'(5,6) A'(5, 9) A'(-1, 6) How Do You Use Coordinates to Translate a Figure Vertically? Watch the video and take notes. Use this information to answer the questions below. Vertical Moves To move up or down, making a "vertical translation", what happens to the x-coordinates? they are changed by addition they stay the same they flip To move up or down, making a "vertical translation", what happens to the y-coordinates? they y's are changed by using addition the y's stay the same they flip After translating a point C (6, 9) down 4 units (x, y-4), what are the coordinates forpoint C' ? C'(6, 13) C' (2,9) C' (6,5) Learn: Translations on a Coordinate Plane Practice Play multiplayer quizzes! Let's See What You Have Learned?
