Question

what kind of triangle is this?
equilateral
isosceles but not equilateral
scalene

Explanation:

Step1: Check for equilateral triangle

An equilateral triangle has all three sides equal. Here, \(12
eq14
eq15\), so it is not equilateral.

Step2: Check for isosceles triangle

An isosceles triangle has at least two sides equal. Since \(12
eq14
eq15\), it is not isosceles.

Step3: Define scalene triangle

A scalene triangle has all three sides of different lengths. As \(12\), \(14\), and \(15\) are all different, it is scalene.

Answer:

scalene
