Assume triangle TRI was dilated to become the image of triangle TAN. Is the dilation an expansion or contraction?

My math teacher told my class to "steal" a 6th grade fraction word problem from the internet, word problems? : -p requirements: only a 1 step word problem. needs to be complex.

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer

A(1,1) b(-3,0) c(-4,-1) d(3,-2) drag it to correct position
