Triangle D: Base has length of 6 cm, and the base angles are 50 degrees.

Answer 1

Triangle A and Triangle B

Explanation:

I think this is the answer because Triangle A, has a unique that all sides have a measure of 60 degrees. And I also think that Triangle B is unique because It's an Equilateral triangle, which means that all sides have the same length.

So hence, I think the answer is A and B
