It is a scalene triangle that has 3 sides of different lengths
No. An isosceles triangle has, by definition, two sides of equal length. A scalene triangle has, by definition, no sides of equal length. So, by definition (and the fact that 0 is not 2), an isosceles triangle cannot be scalene.
The Community answer is sheer nonsense.A triangle can have 3 (equilateral), 2 (isosceles) or 0 (scalene) equal sides.
0 sides
A triangle has no parallel sides.
It's impossible for a triangle to have 2 obtuse angles. A scalene triangle in one that has no equal angles or sides. It could have 1 obtuse angle or it could have 0.
a scalene triangle has 0 lines of symmetry. Scalene triangles are triangles with no sides the same so it can't have a side of symmetry. That is why their are 3 different types of triangles
There cannot be a triangle which has 2 equal sides and 3 equal angles. The number of sides and angles which are equal must be the same: 0, 2 or 3.
You can classify a triangle by its sides, or by its angles.To classify a triangle by its sides:1- A triangle with three sides that are equal in length is called an equilateral triangle.2- A triangle with two sides of the same length and one different is called an isosceles triangle. 3- A triangle with no sides of equal length is called a scalene triangle. To classify a triangle by its angles: 1- A triangle with three angles that are greater than 0 and less than 90 degrees is called an acute triangle.2- A triangle with one angle that is 90 degrees exactly is called a right angle triangle.3- A triangle with one angle that is greater than 90 degrees is called an obtuse triangle.
An isosceles triangle has no parallel sides but it does have 2 sides of equal lengths
no it has no sides that are the same * * * * * In mathematics, the word "normal" is used to mean perpendicular (or at right angles). In that context, a scalene triangle will be a normal, or right angled triangle if its angles are (90, A and 90-A) degrees where 0<A<90. If by "normal" you mean "ordinary" or "nothing special about it" then the answer is yes.
3 sides equal = equilateral (if and only if three angle equal and each = 60 degrees); 2 sides equal = isosceles (if and only if the two angles that are opposite these sides are equal. And that implies they must be acute); 0 sides equal = scalene (if and only if all angles also different). "If and only if" is a mathematical device to say that each of the two statements implies the other, or that they are equivalent.
