Triangle PQR is shown here: O | P ------------ Q \ R / \ / \ / \ / O The rule [1.5x, 1.5y] would mean that for the triangle PQR, the x-coordinate and y-coordinate of each vertex would be multiplied by 1.5. Therefore, the corresponding measurements of the resulting triangle after applying the rule would be 1.5 times the measurements of the original triangle PQR. This would mean that the side lengths, perimeter and area of the new triangle would be 1.5 times larger than the original triangle. However, the angle measures of the original triangle would remain the same after the transformation because they are not dependent on the coordinates. Therefore, the angle measures of the new triangle would be the same values as the original triangle.
