Answer:
C. Same shape
D. Similar
Explanation:
All three angles in ∆ABC are congruent to all three corresponding angles in ∆DEF. However, the three corresponding sides of both ∆s are not the same but they are proportional to each other.
This implies that, both triangles are similar.
Similar triangles have the same shape but different size.
Thus, ∆ABC and ∆DEF can be referred to as being similar and also having the same shape.
