Question

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

Explanation:

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. In the given triangle, two sides are marked as equal (by the tick marks), and the third side is different. So it is an isosceles triangle (as it has two equal sides) but not equilateral (since not all three sides are equal).

Answer:

isosceles, but not equilateral
