### Is a scalene always isosceles?

No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.

Never

### How many angles do a acute isosceles triangle have?

It doesn't matter if a triangle is isosceles, scalene, obtuse, acute... There are always 3 angles in a triangle (which add up to 180).

### Is a scalene triangle always a isosceles?

No, those are two different types of triangles. An isosceles triangle has two sides of the same length and one side of different length; a scalene triangle has three sides which are all of different length.

### A scalene triangle is how many degrees?

For any triangle, be it 'Scalene, Equilateral, Isosceles, Right-angled', the sum of the interiod angles is ALWAYS 180 degrees.

no

### What is the sum of dergrees in a triangle?

the sum of the internal angles of a triangle, no matter whether isosceles, equilateral or scalene, is always 180 degrees

### What triangle is formed with three sides of different lengths?

A scalene triangle. In a scalene triangle, there are no congruent sides or angles. In an isosceles triangle, at least two congruent sides and angles. In an equilateral triangle, all three sides and angles are congruent, with angles that always measure sixty degrees. Note: an equilateral triangle also classifies as an isosceles triangle, as it meets the definition of an isosceles triangle mentioned above.

### What is the name for a triangle that has two sides of equal length?

This triangle is called a scalene triangle.

### How are equilateral isosceles and scalene different?

Equilateral triangles have all sides and angles equal, isosceles triangles have two sides and angles equal, and scalene triangles have no sides or angles equal. In other words, equilateral triangles are a special case of isosceles triangles, and isosceles triangles are a special case of scalene triangles.

### Are a scalene triangle and an isoceles triangles sometimes always or never similar?

Sometimes similar but it depends

### Is a obtuse a scalene in a triangle?

The definition of an obtuse triangle is a triangle with an angle exceeding 90o. A scalene triangle is a triangle in which no two sides are of equal length. Therefore, it is possible that an obtuse triangle is a scalene triangle. However, it is also possible for an obtuse triangle to be an isosceles, in which two sides are of equal length. On a final note, it is impossible for an obtuse triangle to be an equilateral; equilateral triangles always have angles of 60o.
