isosceles
equilateral
scalene

Explanation:

Step1: Recall triangle classification by sides

A triangle is isosceles if it has at least two equal sides, equilateral if all three sides are equal, and scalene if all sides are different.

Step2: Analyze the given triangle's sides

The side lengths are 2, 2, and 3.4. We can see that two sides have length 2 (they are equal), and the third side is 3.4 (different from 2).

Step3: Determine the triangle type

Since there are two equal sides, the triangle is isosceles.

Answer:

Isosceles (corresponding to the "Isosceles" option)
