Explanation:

Step1: Recall triangle side - classification definitions

• 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.

Step2: Analyze the given triangle (by angles, but angle - side relationship in triangle classification)

In a triangle, if two angles are equal (marked with the same arc), then the sides opposite those angles are equal. Since there are two angles marked as equal (but not all three), the triangle has two sides equal.

Answer:

isosceles but not equilateral
