A coordinate rule looks like: (x, y) ( , 2. (4 part question) Reflect Triangle ABC across the y-axis Pre-image Points: A(1, -4) B(2, -1) C(6, -4) A. What is the coordinate rule for a reflection across the y-axis ? )
Make sure to label your image points on the graph using prime notation! An isometric transformation preserves congruence meaning the figure stays the same shape and the exact same size B. What are the new image points? A’(__-1__, _-4___) B’(_-2___, _-1___) C’(_-6___, _-4___) C. Now plot the image on the graph below: Double click the picture to use Paint. D. Was this transformation isometric ? Yes or No Yes Keep going on to next page!
Q1W3 - 1.3 Reflections Dropbox Assignment [Unit 1 : Transformations] Your Turn: (This one is on your own – Draw a graph if you get stuck ) 3. Given ∆ABC has vertices A(2, -3), B(5, -4), and C(2, 1). What will be the vertices of ∆A’B’C’ when ∆ABC is reflected over the x-axis? What is the coordinate rule for a reflection across the x-axis ? (x,y)->(x,-y) What are the new image points?
End of Course Test (EOC) Weekly Practice Question Example: Click here for a video explaining the example Your Turn: 4. Quadrilateral BCDE is shown on the coordinate grid. Keisha reflects the figure across the line y=x to create B’C’D’E’. Double click the graph below to draw in quadrilateral B’C’D’E’ Hint: The coordinate rule of a reflection across the line y = x is: (x, y) (y, x)
