What is the name of the triangle in which none of the sides have the same length?

When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle. When two triangles are congruent it means that they have the same size and shape.                                                                                                                                  please make me brainliest
