this triangle is NOT an equilateral triangle

Step-by-step explanation

an equilateral triangle is a triangle in which all three sides have the same length

Step 1

compare the measures


\begin{gathered} 16\text{ milimeters} \\ 16\text{ milimeters} \\ 15\text{ milimeters} \end{gathered}

a side is different (15 mm) so , this triangle is NOT an equilateral triangle

A triangle has side lengths of 16 millimeters, 16 millimeters, and 15 millimeters-example-1
