Name the types of following triangles :
Triangle with lengths of sides 7 cm, 8 cm and 9 cm.

Answer

To determine the type of triangle with side lengths of 7 cm, 8 cm, and 9 cm, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given sides**: We have three sides of the triangle:
- Side A = 7 cm
- Side B = 8 cm
- Side C = 9 cm

2. **Check the lengths of the sides**: Compare the lengths of the three sides to see if they are equal or not.
- Side A (7 cm) is not equal to Side B (8 cm).
- Side A (7 cm) is not equal to Side C (9 cm).
- Side B (8 cm) is not equal to Side C (9 cm).

3. **Determine the type of triangle**:
- Since all three sides are of different lengths (7 cm, 8 cm, and 9 cm), the triangle does not have any equal sides.

4. **Conclude the type of triangle**: A triangle with all sides of different lengths is classified as a **scalene triangle**.

### Final Answer:
The triangle with side lengths of 7 cm, 8 cm, and 9 cm is a **scalene triangle**.
