This triangle is classed as a scalene triangle.
There are three types of triangles equilateral, isosceles, and scalene.
An equilateral triangle is one that has equal side lengths and degree angles, which this doesn't so thats crossed off. An isosceles triangle is where two sides and angles share the same length and degree angles respectively, therefore thats crossed of. Finally theres a scalene triangle where all sides and degree angles are different, which is what this triangle is
