Identify triangle types based on side lengths in this educational worksheet.

To solve the problem, we need to identify each triangle as scalene, isosceles, or equilateral based on the lengths of their sides. Here's a step-by-step explanation:

Definitions:

1. Equilateral Triangle: All three sides are equal.
2. Isosceles Triangle: At least two sides are equal.
3. Scalene Triangle: All three sides are different.

Step-by-Step Analysis:

#### Triangle 1:
- Sides: 3 in, 3 in, 3 in
- All three sides are equal.
- Type: Equilateral

#### Triangle 2:
- Sides: 5 cm, 4 cm, 2 cm
- All three sides are different.
- Type: Scalene

#### Triangle 3:
- Sides: 3 m, 4 m, 5 m
- All three sides are different.
- Type: Scalene

#### Triangle 4:
- Sides: 4 in, 4 in, 3 in
- Two sides are equal (4 in, 4 in).
- Type: Isosceles

#### Triangle 5:
- Sides: 4 in, 3 in, 3 in
- Two sides are equal (3 in, 3 in).
- Type: Isosceles

#### Triangle 6:
- Sides: 2 in, 2 in, 2 in
- All three sides are equal.
- Type: Equilateral

Final Answer:

1. Equilateral
2. Scalene
3. Scalene
4. Isosceles
5. Isosceles
6. Equilateral

\boxed{\text{Equilateral, Scalene, Scalene, Isosceles, Isosceles, Equilateral}}
