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.

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.

Triangles can be classified by their sides: equilateral, isosceles, scalene or by their angles: acute, right, obtuse. Combinations are possible.

There are three basic types of triangles. Equilateral triangles have three congruent (equal) sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the two angles opposite those sides are also congruent. Scalene triangles have no congruent sides or angles. Right triangles are another type of triangle and they have one ninety-degree angle. Right triangles can either be scalene or isosceles.

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.

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.

The three basic types of triangles are equilateral, isosceles, and scalene. An equilateral triangle has three congruent (equal) sides and three sixty-degree angles. An isosceles triangle has two congruent sides and the two angles opposite those sides are also congruent. A scalene triangle has no congruent sides or angles.

Equilateral, Isosceles and Scalene are three types of triangles classified based on how many congruent sides the triangle has.

A triangle is a 2-dimensional closed shape (called a polygon) with 3 sides. The three sides form a closed shape with three interior angles, hence the name "tri-angle." There are three general types of triangles: they are called Acute, Obtuse, and Right Triangles. Acute Triangles contain interior angles that are all less than 90 degrees. Obtuse Triangles contain one (and only one) interior angle that is greater than 90 degrees. Right Triangles contain one (and only one) angle that is exactly 90 degrees. There are also sub-types of triangles; the most common sub-types are Equilateral and Isoscles Triangles. The interior angles of Equilateral Triangles are all 60 degrees. At least two interior angles of Isoscles Triangles are equal to each other.

All triangles need at least two acute angles

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.

-- both types of triangle are plane (2-dimensional) figures-- both types of triangle have three sides-- both types of triangle have three interior angles that add up to 180 degrees-- in both types of triangle, sin(A)/a = sin(B)/b = sin(C)/cThose are the only characteristics shared by isosceles and scalene triangles.
