Answer:
1st: False
2nd: True
Explanation:
Note:
The similarity ratio of two triangles can only be determined if the corresponding side lengths are in proportion.
If only the angles are given, then there is no way to know the lengths of the sides, and therefore the similarity ratio cannot be determined.
For 1st question:
Sides are not given,
So, the answer is False.
For 2nd question:
Sides are given,




Since all the sides length are proportional.
So, the answer is True.
