No, to form a triangle, the two smaller lengths must add up to be more than the other length.
Scalene, right triangle.
1 = 1 3 = 1 + 2 6 = 1 + 2 + 3 10 = 1 + 2 + 3 + 4 15 = 1 + 2 + 3 + 4 + 5 this is how we work out triangular numbers. It is the number of dots that when drawn form a triangle The formula for the nth triangular number is n(n+1)/2
The formula for a triangle is (1/2)(base)(height). (1/2)(3)(2) = 3 square units.
Scalene Triangle
In mathematics Pascal's triangle is a geometric arrangement of the binomial coefficients in a triangle. 1 (1+0=1) 1 1(1+1=2) 1 2 1 (2+1=3) 1 33 1 (3+3=6) (3+1= 4) 1 4 6 4 1 .....
The formula for a triangle-base pyramid (a form of tetrahedron) isV = 1/3 Bh where B is the area of the triangular baseFind the area of the base by the formula B = 1/2 bh (height of that triangle), then multiply by 1/3 of the pyramid'sheight.
Oh, what a happy little question! To see if these numbers can be the sides of a right triangle, we can use the Pythagorean theorem: a^2 + b^2 = c^2. If 1^2 + 2^2 = 3^2, then they can form a right triangle. Let's take our time and see if these numbers create a lovely right triangle together.
-2, 1, 3
The ability for three lengths to form a triangle is determined by the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides must be greater than the length of the third side. If this condition is not met, the lengths cannot connect to form a closed shape, resulting in an invalid triangle. For example, lengths of 3, 4, and 5 can form a triangle because 3 + 4 > 5, 3 + 5 > 4, and 4 + 5 > 3. Conversely, lengths like 2, 2, and 5 cannot form a triangle because 2 + 2 is not greater than 5.
No triangle can have more than one obtuse angle. If it has one, then it's an obtuse triangle.

Area of the triangle (1/2 x base x height) =1/2 x 2 km x 3 km = 3 km2
