(Last Answer) You will never use this in life O.O....just know the right angle triangle...cause all the laws revolve around it, and the rest revolve around non right angled triangles...like cosine and sine laws...
don't know if your teacher will like this but its garbage...they should be drilling into you that a triangle has three sides and that the total internal angle formed by the the sides is always 180...
No, but it is possible for them to be. An obtuse triangle has 1 angle which measures greater than 90 degrees. A scalene triangle has all different lengths in size. It is possible for a triangle to have different angles, with one above 90 degrees, and have all different side lengths.

What are some triangles?
isocles, equilateral, obtuse, acute, scalene, right
What traingle don't have a right angle?
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
Are the exterior angles of a scalene triangle always obtuse?
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.
What are the kinds of triangles according to measure of their sides and angles?
They are: equilateral, isosceles, obtuse, scalene and right angle triangles
How do you classify triangles in two different ways?
Triangles are classed as: scalene, right angle, obtuse, isosceles and equilateral
