A Reuleaux triangle is a shape that, like a circle, has a constant width. Unlike standard polygons, its sides are outward curves rather than straight lines, the curve a maximum directly across from each vertice.
If a triangle is obtuse, the orthocenter of the triangle actually lies outside of the triangle. If the triangle is acute, the orthocenter of the triangle lies on the inside of the triangle
A triangle can be constructed into any of the given formats.
If a triangle has a right angle, it is a right triangle.

You can list them in any order. There is no standard.

A scalene triangle is one where all the angles are different and all the lengths of the sides are different. A standard 3, 4, 5 triangle does fit the definition of a scalene triangle, but we would alway refer to it in the more specific case, in this case a right angled triangle.
In standard geometry, a triangle with none of its interior angles the same is scalene. Recall those three angles must sum to 180 degrees. Other triangle types include isoceles and equilateral.
