- A triangle with three sides all congruent to each other is an equilateral triangle.
- A triangle with two of its sides congruent to each other is an isosceles triangle.
If you have a triangle with sides {a1,b1,c1} and another triangle with sides {a2,b2,c2} and: a1 = a2; b1 = b2 & c1 = c2, then these two triangles are congruent.

A type of triangle with no equal sides?
There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.
How many congruent sides and angles do equilateral triangles have?
Equilateral triangles have three congruent sides and three congruent angles
How many congruent sides are in an equilateral triangle?
3 because equilateral triangles are triangles that have 3 congruent sides.
If two triangles have a congruent angle and two congruent sides then are the triangles guaranteed to be congruent?
Only if the congruent angle is the angle between the two congruent sides (SAS postulate).
What are the properties of the different types of triangle?
There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
