Question

which triangle is the original triangle, and which triangle is the dilation?
original triangle: ade
dilated triangle: aed
original: ade
dilated triangle: abc
original triangle: abc
dilated triangle: acb
original triangle: abc
dilated triangle: ade

Explanation:

A dilation with a scale factor greater than 1 produces a larger figure, while a scale factor between 0 and 1 produces a smaller figure. The problem notes the scale factor is $\frac{1}{2}$, so the dilated figure is smaller than the original. Triangle ABC is larger than triangle ADE, meaning ABC is the original, and the smaller ADE is the dilated figure.

Answer:

D. Original Triangle: ABC, Dilated Triangle: ADE
