Question

triangle FDP is redced with a scale factor of 1/2 and center of 0,0 find the coordinates of the new coordinates of the vertex

Answer 1

I don't see the original vertex coordinates. For a dilation (scale) of 1/2 about the origin (0,0) each vertex (x,y) is sent to (x/2, y/2).

So if F = (x1,y1), D = (x2,y2), P = (x3,y3) then the image vertices are
- F' = (x1/2, y1/2)
- D' = (x2/2, y2/2)
- P' = (x3/2, y3/2)

Example: if F = (2,6), D = (4,0), P = (−2,3) then F' = (1,3), D' = (2,0), P' = (−1,1.5).

Give the original coordinates and I’ll compute the exact new coordinates.
