Determine the type of triangle that has side lengths of 18, 24, and 42. scalene triangle isosceles triangle equilateral triangle it's not a triangle.

It is not a triangle.

The two shortest side lengths add up to 42, which is the length of the longest side length. If this is true, the two shortest sides will just lay on top of the longest side and not form any interior angles or form a closed figure, thus there is no triangle formed.

Hope this helps!
