The third side must be longer than 11 and shorter than 19.
15 , 12 , 13 - apex
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.
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
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.
Simply measure them.
To create a triangle, the sum of the two shorter sides must be greater than the third side.If 12 is the longer side then the missing side must be greater than 12 - 7 = 5If the missing side is the longer side then the missing side must be less than 12 + 7 = 19Thus any length that is greater than 5 and less than 19.
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.
A triangle has two sides of lengths 7 and 9. what value could the length of the third side be?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
A triangle has 3 sides. The sum of any two sides must be larger than or equal to the length of the third side, and the difference of any two sides must be less than or equal to the length of the third side.
An isosceles triangle has 3 sides 2 of which are equal in length
An isosceles triangle is one in which two sides are of the same length, but the third is different.
The sum of the two shorter sides of a triangle must be longer than the third. Thus the third side can be any length greater than 0 and less than 20. Examples are 0.5, 2, 5, 10, 15, 17.5, 19.9.
The length of the third side is the same as the length of either of the other two sides.
7cm
10
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
