A triangle has side lengths of 16 feet, 9 feet, and 18 feet. Is this triangle equilateral?yesnoSubmit

To determine if a triangle is equilateral, we need to check if all its sides are equal. An equilateral triangle has three sides of equal length.

Step 1: List the side lengths

• Side 1: 16 feet
• Side 2: 9 feet
• Side 3: 18 feet

Step 2: Check for equality

An equilateral triangle requires that: $\text{Side 1} = \text{Side 2} = \text{Side 3}$

Step 3: Compare the side lengths

• $16 \text{ feet} \neq 9 \text{ feet}$
• $16 \text{ feet} \neq 18 \text{ feet}$
• $9 \text{ feet} \neq 18 \text{ feet}$

Final Answer

Since all the side lengths are not equal, the triangle is not equilateral. Therefore, the answer is no.
