Question

what kind of triangle is this?
19
16
14
equilateral
isosceles but not equilateral
scalene

Explanation:

• An equilateral triangle has all three sides equal. Here, the side lengths are 14, 16, and 19, so it's not equilateral.
• An isosceles triangle has at least two sides equal. Since no two sides are equal (14≠16≠19), it's not isosceles.
• A scalene triangle has all three sides of different lengths. As 14, 16, and 19 are all different, this triangle fits the definition of a scalene triangle.

Answer:

scalene
