Question

A triangle has one side measuring 16 inches and two sides measuring 13 inches. Is this triangle scalene?

yes
no

Answer 1

No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.

Answer 2

no

Explanation:

A triangle is scalene when its sides have three different lengths. Your triangle has two sides with the same measure, so it is isosceles, not scalene.
