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.

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.
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.
No because they are different types of triangles
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.

They are both different types of triangles one has 3 equal sides and the other has 2 equal sides.

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.

Many different types, but mostly equilateral triangles.
There are three different types of triangles; equilateral, isosceles, and obtuse triangles.
They are rigid structures: the side lengths determine their shape uniquely. This is one reason that triangles are used in structures - for bracing,
There are two questions that have been mixed up here. There are three "main" types of angle: Acute, Obtuse and Reflex. Acute angles are from 1 to 89 degrees, Obtuse angles from 91 to 179 and Reflex angles anything over 181 degrees. An angle of 90 degrees is a right angle, and an angle of 180 degrees is just a line. There are three types of triangle: Equilateral, Isosceles and Scalene. Equilateral triangles have all three sides the same length (and the angles are all 60 degrees), isosceles triangles have two equal-length sides of length and two equal angles, and scalene triangles have all three sides different lengths, and all three angles are different.
