A triangular number pattern is a type of dot pattern where we create a number series representing the number of dots required to formequilateral triangles. Here, thesidesof the triangles will have thesame numberof dots. 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78… is a triangul...
(d) A formula for d, in terms of p (th e number of sides) an d n is$$ d = ( p - 2 ) n - p + 3 . $$By substituting appropriat e values for p, show that this formula gives(i) th e formula for dotty triangles,$$ d = ( 3 - 2 ) n - 3 + 3 l e a d ...
The th square number is equal to the sum of the st and th triangular numbers, (4) (5) as can seen in the above diagram, in which the st triangular number is represented by the white triangles, the th triangular number is represented by the black triangles, and the total number ...

When working with multiple triangles, each triangle is assigned a triangle number. For example, triangle one (T1) has a triangular number of one. Triangle three has a triangular number of six. The letter T, followed but a number represents a certain triangle. The formula to calculate the ...
Q. Number of quadrilaterals that can be made using the vertices of the polygon of sides 'n' if exactly two adjacent sides of the quadrilateral are common to the sides of the n-gon is View Solution Find the number of triangles which can be formed having vertices at angular points of a ...
First of all we have to sort the array. We will count the number of bad triangles. A bad triangle is defined as a tuple (i, j, k), with i < j < k and L[i] + L[j] < = L[k] (where L[i] = length of the i-th stick). We notice that th...
All triples generated in this way lead to triangles having a hypotenuse that is one unit longer than the larger leg. A more general method consists of choosing integers u and v, one of which is odd and the other even, such that u and v have no common divisors other than the number 1...
