Triangle abc is being dilated with the center of dilation at the origin. the image of c, point c’, has coordinates of (7.2, 3.6). what is the scale factor of the dilation and what are the coordinates of point a’?

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

When a rectangle is dilated, how do the perimeter and area of the rectangle change?
