Answer:
Step-by-step explanation:
Lin drew a triangle and a dilated triangle with a scale factor of .
That means image of the original triangle is smaller than the preimage.
1). Center of dilation will be point A.

Scale factor = =
AD =
So the center of dilation is point A.
2). Since triangle ADE is half of the triangle ACB, triangle ACB is preimage (original) and triangle ADE is an image after dilation.
