Question

which kind of triangle is shown?
scalene triangle
isosceles triangle
equilateral triangle
acute triangle

Explanation:

A scalene triangle has all sides of different lengths, which matches the triangle shown (all sides appear to be unequal in length). An isosceles triangle has two equal sides, an equilateral triangle has all equal sides, and an acute triangle has all angles less than 90 degrees (the triangle has an obtuse angle, so this does not apply).

Answer:

scalene triangle
