The coordinates of the vertices of a quadrilateral are P (2, 4), Q (4,8), R (-2, 6), and S (-4, 2). Quadrilateral PQRS is dilated by a scale factor of 1.5 with the origin as the center of dilation to create quadrilateral P'QʻR'S'. The
Then quadrilateral P'QʻR'S' Is dilated by a scale factor of į with the origin as the center of dilation to create
quadrilateral P"Q"R"S".

Which statement is true?

linear pair postulates

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
