congruence means, the figures are a duplicate or an exact twin of the other, that is angles as well as sides are the same, well, clearly ABC is larger, so they're not congruent.
That said, we could have a figure with same angles, and another with the same angles, but their side are not restricted due to the angle, the sides can easily extend or shrink, whilst the angles are being retained all along, and thus the figures being similiar, but never congruent.
