Feedback
Adds the vector components: 3+5=8 and -2+4=2.
x+7 and y+3 gives (1+7, 2+3) = (8,5).
Translations preserve congruence, i.e., shape and size remain unchanged.
Translation by (0, -6) moves every point down by 6.
Translation is a slide, no rotation or reflection.
Subtract 2 from x and add 5 to y: 4-2=2, -3+5=2.
Translation uses the movement vector, here (3,7).
Shift right by 5 in x: 2+5=7.
Translations preserve orientation; no rotation occurs.
Zero translation leaves every point unchanged.
Translation shifts every point equally without changing orientation.
A mirror image across a line is a reflection.
Turning around a point is rotation.
Dilation scales size relative to a center.
Moving without rotation or resizing is translation.
Enlargement about a center is dilation.
Rigid motions preserve size and shape.
Reflection flips across a line, altering orientation.
Translations and rotations are isometries maintaining size.
Rotating a shape around a point is a rotation.
