∙ 8y agoA scalene triangle is one that has no two equal sides. Therefore, most properties that apply to triangles in general also apply to scalene triangles in particular - for example, the fact that the sum of the angle measures is equal to 180 degrees, the triangle inequality, etc. Among other things, you can find information about triangles in the Wikipedia article on "triangle".

How can a scalene triangle be acute?
When an angle of the scalene triangle is less than 90 but the other two are always more.
What is the numbers for a scalene triangle?
They can be anything at all, just as long as no two of them are the same. If that happens, then you don't have a scalene triangle any more.
What is the difference isosceles triangle and a scalene?
An isosceles triangle has two (or more) sides of equal length, while a scalene triangle has no correlation between side lengths/angle size.
Is a triangle an isosceles triangle and why?
A triangle can be an equilateral triangle, an isosceles triangle, a scalene triangle, a right triangle, an acute triange, or an obtuse triangle.See related link below for more info on triangles
A triangle with side lengths of a b and c is which type of triangle?
You must have more information to determine what type of triangle it is. If two of the lengths are equal, it is isosceles. If all three of the lengths are equal, it is equilateral. If none of them are equal, it is scalene. It may also be a right triangle if it is isosceles or scalene.
How can a scalene triangle be acute?
When an angle of the scalene triangle is less than 90 but the other two are always more.
What is the numbers for a scalene triangle?
They can be anything at all, just as long as no two of them are the same. If that happens, then you don't have a scalene triangle any more.
Is a scalene triangle is a right triangle?
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.
What is the difference isosceles triangle and a scalene?
An isosceles triangle has two (or more) sides of equal length, while a scalene triangle has no correlation between side lengths/angle size.
Can an obtuse triangle be a scalene triangle?
Yes, because as long as one of the triangle's angles are more than 90 degrees and the other 2 are different, it is obtuse and scalene. For example, since all triangle's angles add up to 180 degrees, if a triangle had the angles: 100,30, and 50, it would be obtuse and scalene.
How many right angles does a scalene triangle have?
A scalene or any other kind of triangle can have no more than one right angle.
What is one way in which an isosceles triange and a scalene triange are different?
An isosceles triangle has 2 or more congruent sides and angles. A scalene triangle has 3 completely different sides and angles.
Is a triangle an isosceles triangle and why?
A triangle can be an equilateral triangle, an isosceles triangle, a scalene triangle, a right triangle, an acute triange, or an obtuse triangle.See related link below for more info on triangles
What type of triangle is ABC?
You must have more information about the triangle. If you know the angles, and two of them are equal, it is an isosceles triangle. If all three of the angles are sixty-degrees, it is an equilateral triangle. If none of the angles are the same, it is a scalene triangle. If one of the angles is ninety degrees, it is a right triangle (right triangles may also be scalene or isosceles). If you know the side lengths and two of them are equal, it is isosceles. If they are all equal, it is equilateral. If none of them are equal, it is scalene. A scalene or isosceles triangle may also be a right triangle, which you could determine from side lengths using the pythagorean theorem.
What especial about a scalene triangle?
Forget math, pay more attention in English class.
A triangle with side lengths of a b and c is which type of triangle?
You must have more information to determine what type of triangle it is. If two of the lengths are equal, it is isosceles. If all three of the lengths are equal, it is equilateral. If none of them are equal, it is scalene. It may also be a right triangle if it is isosceles or scalene.
What is a triangle with two or more congruent sides?
No congruent sides is a scalene, two congruent sides is an isosceles triangle, three is an equilateral.
