For a triangle to exist, the sum of the two shorter sides must be longer than the longest side.
If 15 is the longest side, then the other, missing, shorter side must be greater than 15 - 4 = 11.
If the third, missing, side is the longest side, then it must be less than 15 + 4 = 19
So the third side is any length greater than 11 and less than 19.
Examples include 12, 13, 15, 11.5, 18.5.
A triangle has two sides of lengths 10 and 14. What value could the length of the third side be
Triangles are not classified by the length of their sides, but by their shapes. A right triangle, for example, is a triangle which includes one 90o angle. This is true regardless of the size of the triangle; it could have sides a thousand miles long or a thousandth of an inch long and still be a right triangle, as long as it has that 90o angle. An equilateral triangle has three sides which are all of the same length. This is true, again, regardless of the size of the triangle. The three sides could all be a million miles long, or they could be microscopic, but if they are all the same length, then the triangle is equilateral.It would be better to ask about classifying triangles by the relative lengths of their sides.If all the sides are different lengths, we class it as a Scalene Triangle. (Note that all three angles also are different.)If exactly two sides have the same length we call it an Isosceles triangle (Note that two of the angles also are the same size. And try to get the spelling right!!!)If all three sides are the same length, we call it an Equilateral triangle. (If you like you could say that it is a special case of an isosceles triangle). All three angle are the same and they always are sixty degrees each.
5cm, 5cm, and 5cm could represent the lengths of the sides of an equilateral triangle, or might indicate the length, width, and height of a cube.
Triangle inequality says that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.Since 15 + 5 = 20 < 25, we cannot draw a triangle.
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
If the lengths of the two sides of a right triangle on either side of the 90 degree angle are 150 inches and 200 inches, the length of the hypotenuse is: 250 inches.
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
The list that accompanies the question doesn't contain any numbers that could be the lengths of the sides of a triangle.
An EQUILATERAL triangle has all three sides the same length. An ISOSCELES triangle has two sides with the same length. A SCALENE triangle has all three sides different lengths.
If the lengths of its 3 sides are equal then it is an equilateral triangle.
The triangle that has sides of different length is called a scalene triangle.
It is an equilateral triangle that has 3 sides of equal lengths
If all of its sides are the same length its an equilateral triangle. If only two of its sides are the same length it is an isosceles triangle. If all the sides are different lengths it is a scalene triangle
A triangle with no equal side lengths is a scalene triangle.

A triangle with no right angle and sides of different lengths is a scalene triangle.
A triangle has two sides of lengths 7 and 9. what value could the length of the third side be?
They are triangles. An isosceles triangle has two sides that are equal length, and the other side would be a different length. A right triangle could be an isosceles triangle. On the other hand, a scalene triangle has all of its sides different lengths.
