Question

classify this triangle by its sides. equilateral isosceles but not equilateral scalene

Explanation:

• An equilateral triangle has all three sides equal.
• An isosceles triangle has at least two sides equal.
• A scalene triangle has all three sides of different lengths.
• In the given triangle, only two sides are marked as equal (by the tick marks). So it is not equilateral (as not all three sides are equal) and not scalene (as not all sides are different).
