Question

Octagon ABCDEFGH and its dilation, octagon A'B'C'D'E'F'G'H', are shown on the coordinate plane below:

Octagon ABCDEFGH with ordered pairs at A at 2, 1, at B 2, negative 1, C 1, negative 2, D negative 1, negative 2, E negative 2, negative 1, F negative 2, 1, G negative 1, 2, H 1, 2. Octagon A prime B prime C prime D prime E prime F prime G prime H prime with ordered pairs A prime 8, 4, at B prime 8, negative 4, at C prime 4, negative 8, at D prime negative 4, negative 8, at E prime negative 8, negative 4, at F prime negative 8, 4, at G prime negative 4, 8, at H prime 4, 8.

If the center of dilation is at the origin, by what scale factor was octagon ABCDEFGH dilated?

Answer 1

yikes

if you can, try drawing both octagons out and comparing the corresponding side lengths to see what the dilation factor is
