I have a question about reflections. How can you determine what line a point is being reflected over if you just have coordinates?

Question

jim_thompson5910 · Answer

So you just have a set of points and no line of reflection?

anonymous · Answer

Actually three points...one point that is reflected over an undefined line of reflection to yield the second point which is then reflected over another undefined line of reflection to yield the third point.

can you show me what you're looking at?

anonymous · Answer

I need to be able to find the lines

jim_thompson5910 · Answer

can you post a screenshot?

anonymous · Answer

Point #1 is (3, -4), #2 is (1,1), and #3 is (-3,11)

jim_thompson5910 · Answer

ok so you just need to find the midpoints of each segment (connecting point 1 and 2, and connecting point 2 and 3)

also, you'll need the slope of each segment to find the perpendicular slope

Thanks so much that makes sense
