Isosceles triangle
An isosceles triangle
In any triangle that is not equilateral, there will always be a pair of non-congruent sides. This is because, in a triangle, the lengths of the sides are determined by the angles opposite them; if one angle is different from the others, the sides opposite those angles must also be different in length. Hence, in scalene and isosceles triangles (where at least two sides are equal), there will always be at least one pair of sides that are not congruent.

An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
An Isosceles Triangle
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
That is a scalene triangle. An isosceles triangle has at least 2 congruent sides and an equilateral triangle has 3 congruent sides.
A triangle with two congruent sides is an isoscelestriangle. But an equilateral triangle has two congruent sides. (It actually has three congruent sides.) And isosceles triangle is generally described as a triangle with exactly two congruent sides.
A triangle that has at least two congruent sides is called an isosceles triangle. It has two equal sides and two equal angles.
Isosceles Triangle Isosceles TriangleIsosceles triangles have at least 2 congruent sides, and equilateral triangles have all 3 sides equal. A scalene triangle has no congruent sides or angles. All triangles have 180 degrees total.An equilateral triangle has three congruent sides and an isosceles triangle has two congruent sides.
An obtuse triangle does not always have three congruent sides. An obtuse triangle can be any form that always has three angles.
