  1. i learned this in 4th grade too, 2 years ago... i sort of forget it, but ill give it a shot. Rotation is when you rotate something, so its at a different angle, reflection is when the shape or dimension is the reflection of itself,( basically backwards), and translation is the thing i forget, so i'd just check the dictionary for that one. By that way, id just check the other two just in case! :)

    becomes for example
    b

    a

    reflection

    a -- b becomes b - - a


    translation
    a -- b ----> a -- b (moved right)

  3. rotation is when you rotate an anagle, reflection is like flipping an object so its like looking in the mirror
    example: g----h becomes h----g so its like a mirror, and last but not least TRANSLATION!!!thats when you slide an object up down or just sliding it so its in a different spot.
