A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.

An isosceles triangle has 3 sides 2 of which must be equal in length.

There are 3 sides of a triangle and it has 3 interior angles that add up to 180 degreesThe sum of the lengths of the two shorter sides must be greater than the length of the third side.A triangle must have 3 sides, with angles that add to 180degrees. The sides can be any length.

An equilateral triangle, by definition, has three sides of equal length. The definition for an isosceles triangle is that it must have two sides of equal length, the other side being free to have any length. Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.

yes a scalene triangle is a isosceles triangle.* * * * *No. A scalene triangle is not an isosceles triangle. The sides of a scalene triangle must all be of different lengths. In an isosceles triangle two of the sides must be the same length. If all three sides are different (scalene) then two cannot be the same (isosceles).

An isosceles triangle is not a regular triangle because it has 1 side that doesn't equal the other 2. For it to be a regular triangle it will need to have all sides the same length. Here are the three types of triangle classification: In a equilateral triangle or also known as regular triangle "all" sides must have the same length. In an isosceles triangle "at least" two sides must have the same length. In an scalene triangle all sides must be of different lengths Therefor it can be said that a regular triangle is a type of isosceles triangle since it has at least 2 sides of the same length. But remember if one side changes length and 2 remain the same it becomes an isosceles, if all sides are of different lengths then it becomes scalene.

an isosceles triangle has at least two equal sides; an equilateral is technically an isosceles triangle because it has three.

NO but every Equilateral triangle is an Isosceles triangle. That is the difference . Isosceles triangles have only 2 sides the same length. Equilateral have ALL 3 sides the same length which means that they must have 2 sides the same length, so they are a very special case of an Isosceles triangle. That is why they have a special name - Equilateral meaning 'all sides equal'. The word lateral is a reference to the word length.

No because the 3 sides of an equilateral triangle must be the same length.

The length of the third side must be greater than the difference between the length of the two given sides and it must be less than the sum of the two given sides. These limits can be derived from the fact that any two sides of a triangle must have a combined length greater than the third side.

No. Scalene, by definition, is a triangle with no equal sides (or angles). An equilateral triangle must have all sides the same length (and all angles would measure 60Â°).
