(2.01/2.02)A polygon is shown on the graph: What effect will a translation 3 units down and 2 units left have on the polygon? Be sure to address how it could impact the angles, side lengths, and congruency between the original pre-image and the image.

For the answer to the question above, when you carry your jewelry box or your phone 3 floors down

and 2 miles to the left, the angles and side lengths don't change,

and it still looks exactly the same as it did before you picked it up

and moved it.

Translation can't change angles or lengths.  And if those don't

change, then the later shape is congruent to the earlier shape.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
