Only equilateral triangles have all equal sides, also all the angles are 60 degrees.
If two separate triangles have equal side lengths they are said to be congruent. They cannot be a different type of triangle except, possibly, in their orientation.

Which types of triangles can have 2 or more sides with equal lengths?
All triangles have 3 sides but an isosceles triangle has 2 equal sides and an equilateral triangle has 3 equal sides.
Are triangles equilateral?
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
What shape has three different sized sides?
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.
Are scalene and isosceles triangles similar?
No because they are different types of triangles
What are the types of trapezuim?
A trapezium or a trapezoid has one pair of parallel sides of different lengths but an isosceles trapezium also has one pair of parallel sides of different lengths but its sloping sides are equal in length.
Which types of triangles can have 2 or more sides with equal lengths?
All triangles have 3 sides but an isosceles triangle has 2 equal sides and an equilateral triangle has 3 equal sides.
Some equilateral triangles are not isoscles?
They are both different types of triangles one has 3 equal sides and the other has 2 equal sides.

Why might two triangles not necessarily be congruent?
they might be different types of triangles.
How many different types of triangle are there?
For the "catch all" and most broad type of triangles, there are 3: Obtuse - 1 angle > 90° Acute - all angles < 90° Right - 1 angle exactly 90° There are more specific categories, such as isosceles triangles, which can be obtuse, right or acute triangles that contain exactly 2 angles of equal degree, and exactly 2 sides of equal lengths.
What kind of triangles make up a pyramid?
Many different types, but mostly equilateral triangles.
What is an example of a sentence with a triangle in it?
There are three different types of triangles; equilateral, isosceles, and obtuse triangles.
Are equilateral triangle is always an isosceles triangle?
No because they are different types of triangles inasmuch that an equilateral triangle has 3 equal sides whereas an isosceles triangle has only 2 equal sides
Can a traingle be scalene and isosceles?
Yes they are different types of triangles
