The correct Answer is:
To determine the type of triangle with sides measuring 12 cm, 14 cm, and 18 cm, we can follow these steps: ### Step 1: Identify the lengths of the sides We have three sides of the triangle: - Side A = 12 cm - Side B = 14 cm - Side C = 18 cm ### Step 2: Check if all sides are different Next, we need to check if all three sides are of different lengths: - 12 cm (A) - 14 cm (B) - 18 cm (C) Since 12 cm, 14 cm, and 18 cm are all different, we proceed to the next step. ### Step 3: Classify the triangle A triangle can be classified based on the lengths of its sides: - **Equilateral Triangle**: All three sides are equal. - **Isosceles Triangle**: Two sides are equal. - **Scalene Triangle**: All three sides are of different lengths. Since all three sides (12 cm, 14 cm, and 18 cm) are different, this triangle is classified as a **Scalene Triangle**. ### Conclusion The triangle with sides of lengths 12 cm, 14 cm, and 18 cm is called a **Scalene Triangle**. ---
