Triangles Classification
A triangle is a figure formed when three non collinear points are connected by segments. Each pair of segments forms an angle of the triangle. The vertex of each angle is a vertex of the triangle.
Triangles can also be classified by their angles. All triangles have at least two acute angles. The third angle is either acute, obtuse, or right.
Since all sides of an equilateral triangle are congruent, then at least two of its sides are congruent. So, all equilateral triangles are also isosceles triangles. Some parts of isosceles triangles have special names.
