Translation When translating an object we need to remember to keep the same distance and keep the same angle. To keep the same angle, we must maintain parallel lines of translation. If given an arrow of translation, follow these 4 steps– Measure the distance and label the distance on the line. Keeping your ruler parallel to the original line, measure the same distance and plot the new point on the image. (label as prime!) Repeat steps for all remaining points. Connect all new points to create your translated image. Remember: Label all new points as PRIME! Each new point will be the SAME distance from the original and maintain the SAME angle as the original object. JOURNAL: Students need to measure the distance of the arrow. Label the distance. The arrow tells them in which “angle” direction and how far to slide each point to create its image point.
