Which description is true about the transformation shown? it is a dilation because the transformation is isometric. it is a dilation because the transformation is not isometric it is a stretch because the transformation is isometric it is a stretch because the transformation is not

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

no idea

step-by-step explanation:

the answer is 1030 it's very simple math.
