Only an equilateral triangle are all sides congruent
if it has one congruent side it is a scalene triangle. if it has a pair of congruent sides it is an isosceles triangle. if all the sides are congruent it is an equilateral triangle
................ scalene triangle ................ =)
If triangle DEC is congruent to triangle BEC by the principle of CPCTC (Corresponding Parts of Congruent Triangles are Congruent), then all corresponding sides and angles of the two triangles are equal. This means that side DE is equal to side BE, side EC is equal to side BC, and the angles ∠D and ∠B are congruent, as well as ∠E and ∠C. Thus, any corresponding part from one triangle can be stated to be congruent to its counterpart in the other triangle.
Scalene triangle - a triangle where none of the sides are the same length.Isosceles triangle - a triangle where two sides of the triangle, or the legs, are the same lengthEquilateral triangle - a triangle with all side lengths congruent and all included angles congruent
A scalene triangle.
if it has one congruent side it is a scalene triangle. if it has a pair of congruent sides it is an isosceles triangle. if all the sides are congruent it is an equilateral triangle
An equilateral triangle has three congruent sides.
A triangle with all the sides congruent is called an equilateral triangle. It has three identical side lengths and three identical angles of 60°.

The Side Side Side or SSS postulate says f three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

A scalene triangle.
If a triangle does not have the same length side as another triangle the sides are not congruent.
Scalene triangles have no congruent side lengths.
Someone correct me if I am wrong, but I don't believe triangles can be "equal", only congruent. The measurements can be equal, but not the triangle itself.The triangle congruency postulates and theorems are:Side/Side/Side Postulate - If all three sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Side/Angle Postulate - If two angles and a side included within those angles of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Side/Angle/Side Postulate - If two sides and an angle included within those sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Angle/Side Theorem - If two angles and an unincluded side of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Hypotenuse/Leg Theorem - (right triangles only) If the hypotenuse and a leg of a right triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
Hmm... I'm thinking an equilateral triangle because an equilateral triangle has 3 congruent sides and are all the same length.
