How do you find the length of one side of an isosceles triangle given the length of the other 2 sides?
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)

How are isosceles and scalene different?
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.
How does the isosceles triangle look?
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.)
How is an equilateral triangle an isosceles triangle?
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.
How many equal sides does and an isosceles triangle have?
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)
What is unique in isosceles triangle?
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,)
What is an isosceles and scalene?
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.

What is the difference between an isosceles trapezoid and an isosceles triangle?
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.
Why is equilateral triangle not isosceles?
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.

All isosceles triangles are also equilateral triangles?
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/

What is the base of an isosceles triangle?
The side that is not the same length as the other two sides.
What are two other names for an isosceles triangle?
Two other names for an isosceles triangle are an "isosceles triangle" itself and a "symmetric triangle," as it has two equal sides and angles, creating symmetry. Additionally, some may refer to it simply as a "two-sided triangle" to emphasize its equal-length sides. However, the term "isosceles" is the most commonly used designation.
