If it is 19 sided it cannot be a triangle. The "tri" in the word triangle means 3. So a triangle can have only 3 sides - no more, no fewer!
It is 48.
28 is a triangle number. The 28th triangle number is 406.
The third triangle number is 6.
The fifth triangle number, known as T5 is 15.
No. Triangle numbers are a fixed set of numbers that can't be altered to make one certain number turn into a triangle number.
A triangular number or triangle number counts the objects that can form an equilateral triangle. 10 objects can be formed into an equilateral triangle.

The area of a triangle can be a rational number or an irrational number depending on its dimensions.
The answer depends on the labels of the sides which are 19 and 12.
There are two equal sides of 19 units in the right angled triangle. To find the third side use Pythagoras' theorem: 192+192 = 722. The square root of 722 = 26.87005769 Perimeter of triangle = 19+19+26.87005769 = 64.87005769 Therefore perimeter of triangle rounded to 2 decimal places = 64.87 units.
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.
