    Inversion Through P in Euclidean Plane | Fix(Vp)

    Ok I'm going to write what I came up with, I'm not the best with notation so see if this makes sense to you... Describe Fix(Vp) and proof - I now say that there's only one point fixed in Vp and that's when X=Y=P. Proof: Part 1. Given an element X and and a point P which is X, The inversion...

    Inversion Through P in Euclidean Plane | Fix(Vp)

    The only way I can help you with this question is to give you an example of another composition given a point P not lying on a line L, Reflect point P over line L to give you point P' which is the Rl(p) (the reflection of P.) Then Rl(p) composed of Rl(P) will bring you right back to the...

    Inversion Through P in Euclidean Plane | Fix(Vp)

    Homework Statement If P is a point in E (euclidean Plane) Then the "Inversion through P" is Vp = {(x,y)| x,y in E and either, 1. x=y=p, or 2. p is the midpoint of segment xy}What's Fix(Vp) Show that Vp composed of Vp = The identityHomework Equations The Attempt at a Solution Vp composed of Vp...
