Please answer this asap! Its midnight and I'm tired 40 points

They are the same shape as ABC and LMN both measure 4 base and 4 side measurement each along with hypotenuse shared value of 5. Making these triangles isosceles.

We can see that LMN is the only triangle whos base that lies parallel with the y (inverse usual x line), this is proof that the transition was 270° in total and 222.5° flip from the ABC last transition.

Each transition was the following

1) As shown on diagram 90 flip

We found 67.75° with ABC, then 222.5°  

Meaning 270° from start to finish.

There was a 22.5 transition in the first grid too, so if counting that we deduct that from 270° to equal 247.5° full rotation from first replacement coordinate drawn in question 1.
