Question

Determine which of the triangles below are unique. Share your reasoning.

Triangle A: All angles measure 60 degrees

Triangle B: All sides have length 6 cm.

Triangle C: Two sides have length 6 cm, and the included angle measures 55 degrees

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

Answer 1

Explanation:

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

Answer 2

Explanation:

Triangle A: Equilateral triangle, all angles are equal (60 degrees) and all sides are equal. Unique.

Triangle B: Isosceles triangle, two sides are equal (6 cm) and two angles are equal. Unique.

Triangle C: Not unique, as different triangles can have two sides of equal length and an included angle of 55 degrees.

Triangle D: Not unique, as different triangles can have a base of 6 cm and base angles of 50 degrees.
