For side lengths of any triangles not right angled (that would be the Hypoteneus ^2 = side A^2 + side B^2 ) there are the laws for oblique triangles. They are:
1) The law of Sines: a/ sinA = b/ sinB = c/ sinC. Once you have any 2 side measures and the accompanying angular measure (or 2 angular measures and one side measure), then treat it as a proportion.
2) The law of Cosines: a^2= b^2+c^2 - 2bc (cos a)
3) The law of Tangents: a-b/a+b= tan [1/2 (a-b)] / tan [1/2 (a+b)
An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.
An isosceles triangle has 2 sides the same length, and two angles the same. The other side has a different length. (If all three are the same, it is an equilateral triangle.)
An isosceles triangle has 2 sides of equal length. The other two types are scalene (with no sides of equal length) and equilateral (with all sides equal in 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.
A isosceles triangle has only two sides the same length unlike other types of triangle which either have one or none. If your wondering what triangle has only one side equal it is the isosceles also, (think about it,)
They are triangles. An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.

An Isosceles trapezoid has four sides (is a quadrilateral) with a pair of parallel sides and the other two sides of equal length; whereas An isosceles triangle has three sides with a pair of sides of the same length and the other side a different length.
The definition of an isosceles triangle is that 2 sides are the same length, the other is different. An equilateral triangle means all sides are the same.

No, all isosceles triangles are not equilateral triangles. An isosceles triangle is a triangle that has two sides of equal length. An equilateral triangle is a triangle that has all three sides of equal length. Therefore, it is possible for a triangle to be isosceles but not equilateral. For example, a triangle with sides of lengths 3, 3, and 4 is an isosceles triangle, but it is not an equilateral triangle because all its sides do not have the same length. On the other hand, all equilateral triangles are also isosceles triangles because they have two sides of equal length. My recommendation ʜᴛᴛᴘꜱ://ᴡᴡᴡ.ᴅɪɢɪꜱᴛᴏʀᴇ24.ᴄᴏᴍ/ʀᴇᴅɪʀ/372576/ꜱᴀɪᴋɪʀᴀɴ21ᴍ/

The side that is not the same length as the other two sides.
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.
