Is scalene triangle cannot contain a right triangle?
A scalene triangle CAN also be a right triangle. For a triangle to be scalene, all 3 sides must be of different lengths. If you draw a triangle with a 90 degree right angle (ie. a right triangle) you will see that it's very easy for the sides to be unequal lenghts.
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 three ways in naming a triangle?
Right angle, equilateral, isosceles and there are also scalene and obtuse triangles.
A scalene triangle can also be an what triangle?
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
What is the sum of the measures of the three angles of a scalene triangle?
In a scalene triangle, the angle sum is still 180 degrees. What defines a scalene triangle is that it has three sides with different lengths, and therefore, also different angles. It can be a right triangle for example, with the angles 30, 90, and 60 degrees. It's angle sum always sums up to 180 as in all triangles. Note: It doesn't have to be a right triangle. It can be any kind of triangle as long as it has three different angles and sums up 180 degrees.
Can a scalene triangle also be a right angle triangle?
yes it can be

Is an scalene triangle an obtuse or an right triangle?
A scalene has three sides of unequal lengths, and all threes angles different.The largest angle defines the triangle¹:acute: a scalene triangle could have sides 6, 9, 10right angle: a scalene triangle could have sides 6, 8, 10obtuse: a scalene triangle could have sides 6, 7, 10So a scalene triangle could be any of acute, right angle or obtuse.¹In terms of acute, right angle or obtuse. Triangles can also be defined in terms of their sides: equilateral (all three sides equal), isosceles (two sides equals) or scalene (no sides equal)
What are three ways in naming a triangle?
Right angle, equilateral, isosceles and there are also scalene and obtuse triangles.
Do scalene triangles have three different angles?
Yes. A scalene triangle is, by definition, a triangle with all sides and angles different. An equilateral triangle has all sides and angles the same, an isosceles triangle has 2 sides and 2 angles equal, and a right triangle has a right angle, but it is also possible for an isosceles triangle to be a right triangle.
Obtuse scalene triangle?
its a triangle has 1 obtuse angle greater than 90 degress it also scalene NO equal sides
What is a triangle that has no equal sides and no equal angles?
It is a scalene triangle although a right angle triangle could also fit the given description under certain circumstances.
Can a scalene triangle also be a right-angled triangle?
Yes.
How is a right triangle and scalene triangle different?
A scalene specifies that no two sides and no two angles are equal. A right triangle has one side that is a right or 90 degree angle. A scalene triangle can be a right triangle {a 3-4-5 right triangle or a 30°-60°-90° right triangle, for example}. A scalene triangle can also be an acute or obtuse triangle. Note this: there is only one case of a right triangle, which is non-scalene. This is the isosceles right triangle with angles 45°, 45° & 90°, and sides sqrt(2), 1 & 1. All other right triangles are scalene. The terms scalene, isosceles, and equilateral refer to how the side lengths are related to each other. The terms right, acute and obtuse refer to angles, specifically the largest angle: obtuse - the largest angle is greater than 90°; right - the largest angle equals 90°; acute - the largest angle is less than 90°. The terms referring to angles are not necessarily mutually exclusive with the terms, which refer to side lengths (except for equilateral). So you can have an isosceles obtuse (a shallow pitched roof), or isosceles right (example above), or isosceles acute (a very steep pitched roof).
Does a triangle have any right angles?
If it's a scalene then yes. one. otherwise no. Except an isosceles triangle can also have a right angle between the sides of equal length; the equal angles then being 45o each. A triangle can have at most one right angle.
A scalene triangle can also be an what triangle?
a scalene can be a right-angled triangle or a obtuse angled triangle or a acute angled triangle depending on the angles of the triangle.
