Question

classify triangle (abc) according to its side lengths. equilateral scalene isosceles equiangular

Explanation:

Step1: Recall triangle - type definitions

An equilateral triangle has all sides equal. An isosceles triangle has two sides equal. A scalene triangle has all sides of different lengths. An equiangular triangle has all angles equal (and is also equilateral in Euclidean geometry).

Step2: Analyze the given triangle

From the figure, there is no indication that any of the sides of triangle \(ABC\) are equal. So, it is not equilateral or isosceles. Also, equiangular is not a classification by side - lengths. Since all sides appear to have different lengths, it is a scalene triangle.

Answer:

Scalene
