The diagram shows a dilation of line ab
about the origin o. determine the scale
factor of the dilation by following these steps
steps.
1. measure these lengths:
oa = ? units
oa' = ? units

answer: drop sub on yt channel mighty goat

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
