Question

classify the triangle using its sides.
scalene
isosceles, but not equilateral
equilateral

Explanation:

Step1: Recall triangle classification

A scalene triangle has all sides of different lengths. An isosceles triangle has at least two sides of equal length. An equilateral triangle has all three sides of equal length.

Step2: Analyze the given triangle

From the markings on the sides of the triangle, we can see that no two sides have the same number of marks (which denote equal - length in such diagrams). So, all three sides are of different lengths.

Answer:

scalene
