Area of a square is equal to the product of sides of the square.We are considering a figure in which the midpoints of sides of each square make another square. And so on until a specific number of squares.This figure shows a square made by joining the midpoints of a ... Read More

A rhombus inscribed in a rectangle touches the sides of the rectangle so by this we can infer that the diagonals of the largest inscribed rhombus are equal to the length and breadth of the rectangle.If we have the length(l) and breadth(b) of the rectangle, the length of the diagonal ... Read More

A circle inscribed in a rectangle touches the larger side of the rectangle with its ends i.e. the length is tangent to the circle.A rectangle inscribed in a semicircle touches its arc at two points. The breadth of the rectangle is equal to the diameter of the circle.If R is ... Read More

Anti-Clockwise spiral traversal of a binary tree is traversing the elements of a tree in such a way that if traversed they make a spiral but in reverse order. The following figure shows how a anti-clockwise spiral traversal of binary tree.The Algorithm defined for spiral traversal of a binary tree ... Read More
