An scalene triangle.
To check whether it is possible to have a triangle with side lengths 4cm, 13cm, and 14cm, we use a special rule.The rule is: If you take any two sides of a triangle and add their lengths, the sum of the lengths must be greater than the third side.Test this triangle. 4+13=17, which is bigger than 14. 14+4=18, which is bigger than 13. 13+14=27, which is greater than 4.The rule works for all side combinations, so it is possible to have a triangle like this.So the answer is: yes, you can have a triangle of side lengths 4cm, 13cm, 14cm. (Note that the lengths do not have to be in centimeters, for example they can be 4m, 13m, and 14m)
it is an acute triangle.
By Pythagoras's theorem, to make a right angled triangle, 142 + 152 should be 212 But 142 + 152 = 196 + 225 = 421 whereas 212 = 441 So these three sides cannot make a right angled triangle.
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.
An scalene triangle.
A triangle with side a: 13, side b: 14, and side c: 15 units has an area of 84 square units.
It is an equilateral triangle that has 3 equal sides of 14 cm
No. 5+8 = 13 < 14 Any two sides of a triangle must add to more than the third side.
A triangle tri meaning3 is impossible to have more than 3 sides.

it is an acute triangle.
This is merely a doubling of the 5-12-13 triangle. The sides are 10 and 24 ft.
No
The triangle number of 13 can be calculated using the formula n(n+1)/2, where n is the number you are finding the triangle number of. In this case, n is 13. Plugging 13 into the formula, we get 13(13+1)/2 = 13(14)/2 = 182/2 = 91. Therefore, the triangle number of 13 is 91.
The isosceles triangle has a perimeter of: 14+14+9 = 37 feet
If it only has those 3 sides then it must be a triangle. As all its sides are different lengths it's a scalene triangle.
