Worksheet for identifying types of triangles based on side lengths.

A worksheet titled "Types of Triangles" with six triangles labeled with side lengths, asking students to identify each as equilateral, isosceles, or scalene. The bottom question asks about triangles with at least two equal sides.

Since I can't view or access images directly, I can't see the specific triangles in your uploaded image. However, based on the description of the worksheet you provided — titled "TYPES OF TRIANGLES" — and the instructions, I can guide you through how to solve this type of problem and explain the logic.

🔍 Understanding the Task


You are asked to:
1. Name each triangle by its side lengths.
2. Classify it as equilateral, isosceles, or scalene.
3. Answer a final question:
> "I have at least two sides of equal length. What kind of triangle am I?"

📌 Definitions



| Type | Side Lengths Description |
|-------------|----------------------------------------------|
| Equilateral | All three sides are equal. |
| Isosceles | At least two sides are equal. |
| Scalene | No sides are equal (all sides different). |

> Note: An equilateral triangle is also a special case of an isosceles triangle (since it has at least two equal sides), but typically we classify it separately when all three are equal.

How to Solve Each Triangle



For each triangle shown in the worksheet:

1. Look at the side lengths labeled on the triangle.
2. Compare the lengths:
- If all three sides are the same: → Equilateral
- If exactly two sides are the same: → Isosceles
- If no sides are the same: → Scalene

Let’s assume some examples based on typical problems like this:

#### Example 1:
- Sides: 3 cm, 4 cm, 5 cm → All different → Scalene

#### Example 2:
- Sides: 6 cm, 6 cm, 8 cm → Two equal → Isosceles

#### Example 3:
- Sides: 5 cm, 5 cm, 5 cm → All equal → Equilateral

❓ Final Question:


> "I have at least two sides of equal length. What kind of triangle am I?"

Answer:
Isosceles

> Because the definition of an isosceles triangle is that it has at least two equal sides.

(Although equilateral triangles also meet this condition, the most accurate general answer for "at least two equal sides" is isosceles, since it includes both isosceles and equilateral cases.)

But if the question is asking for the type that fits that description, then the correct choice is:

👉 b) isosceles

Summary



- Fill in each blank under the triangle with:
- equilateral, isosceles, or scalene, based on side lengths.
- For the final question:
> "I have at least two sides of equal length. What kind of triangle am I?"
→ Answer: b) isosceles

If you can describe the side lengths of any specific triangle from the image, I can help classify it directly!
