When a figure is translated on a coordinate grid, what conclusion can you draw from the pre-image and image?

the angles remain the same, and the shape of the figure changes.

the side lengths remain the same, and the orientation of the figure changes.

the angles remain the same, and the size of the figure changes.

the side lengths remain the same, and the position of the figure changes.

When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another.

Emphasize the basic properties of translations:

1. Lines are taken to lines, and line segments to line segments of the same length (this property states that choice C is incorrect).

2. Angles are taken to angles of the same measure.

3. Parallel lines are taken to parallel lines and orientation of the figure remains the same (this property states that choice B is incorrect).

4. The image of a figure under a translation is always congruent to the preimage (this property states that choice A is incorrect).

correct choice is D (prove that using property 1 and definition of translation).

Sry i’m so bad at math! wish i could answer #imdumb
