You can use the size and angles to classify the triangle that is represented.
The peak is an obtuse angle, and the two vertices on the side are acute angles. This makes it an obtuse triangle. If there is one obtuse angle seen, it is classified as an obtuse triangle.
Two of the sides are the same length, and this makes it an isosceles triangle.
