# What is always true about a triangle?

A triangle has 3 sides. A regular triangle has all EQUAL sides. An isosceles triangle has 2 EQUAL sides. A scalene triangle has NO equal sides. Equal = parallel..basically equal and parallel are the same thing, in this conversation.

### In a scalene triangle the longest side is opposite the angle with the largest measure true of false?

True. In any triangle, the longest side is always opposite the largest angle; the shortest side is always opposite the shortest angle; and the middle length side is always opposite the middle size angle. In an isosceles triangle, there is no middle length side; and the two sides of equal length are opposite the angles of equal size. In an equilateral triangle, all sides are the same length, as are all the angles.

### What statement sometimes true about the relationship between acute triangles and isosceles triangle?

### What is the converse of the isosceles triangle theorem?

The converse of "A implies B" is "B implies A". The isosceles triangle theorem states that if two sides of a triangle are the same, then two angles of that triangle are the same. The converse would be: if two angles of a triangle are the same, then two sides of that triangle are the same. The converse of the isosceles triangle theorem also happens to be a provable theorem, but it is not always…
