Question

classify this triangle by its sides. triangle image with two sides marked equal options: equilateral, scalene, isosceles but not equilateral

Explanation:

Step1: Recall triangle classification by sides

Triangles are classified by sides: equilateral (all 3 sides equal), isosceles (at least 2 sides equal), scalene (all sides different).

Step2: Analyze the given triangle

The triangle has 2 sides marked with the same tick (indicating they are equal), and the third side is unmarked (so different from the other two). Thus, it has 2 equal sides (not all 3), so it's isosceles but not equilateral.

Answer:

isosceles but not equilateral
