Right triangles have one right angle. Scalene triangleIs have sides of unequal length. Right scalene triangles combine those aspects.

Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles

Any triangle can have a maximum of one right angle. Most right triangles are scalene triangles. The only non-scalene right triangle is a 45° - 45° - 90° isosceles right triangle. It is not possible to have an equilateral right triangle in plane geometry. A scalene triangle does not have to have a right angle, but it can have one.

No, they are not always obtuse, because a scalene triangle can also sometimes be an obtuse triangle (meaning that one interior angle is obtuse), making one exterior angle acute. Scalene triangles also can be a right triangles (meaning that one interior angle is a right angle), which would make an exterior angle a right angle. Then also they can be acute triangles, in this case all 3 exterior angles are obtuse.

They are: equilateral, isosceles, obtuse, scalene and right angle triangles
