after a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are a (6,3), b'(-2, 1)
and c'(1,7). what are the coordinates of the vertices of the pre-image?

❤️ (geometry) does the construction demonstrate how to copy an angle correctly using technology a) yes; the distance between points a and f was used to create circle h b) yes; the distance between points f and g was used to create circle h c)no; the distance between points a and f was used to create circle h d) no; the distance between points f and g was used to create circle h
