![]() ![]() ![]() Then, draw a diagonal line to the left and down the middle of the page. Then, continue your motion diagonally down and to the right, forming a roof on the box with your fingers. How can you draw a cross in a box without having to move your pen from the page?ĭraw a diagonal line from the top left corner of the box, which should be where the pen should be, towards the upper right corner of the box until you reach the midpoint of the box. It consists of eight small squares, 18 single squares, nine 2 x 2 squares, four 3 x 3 squares, and one 4 × 4 square, all in different sizes. That’s right: it’s not the numbers 8, 16, 24, 28, or 30, and we’ll explain why later. The solution to the problem is 40 squares, which is the right answer. What is the total number of squares in this picture? With another way of putting it, there should either be NO odd nodes or precisely TWO odd nodes. This form can only be drawn without raising your pen or travelling over the same line again if the number of nodes with odd degrees is either zero or two, according to Euler’s theorem. Which figure can be drawn entirely without the use of a pencil? There were 22 related questions and answers found. Consider alternatives to the conventional wisdom. This is the 9-Dot Puzzle! Take a step back and look at the larger picture. Using just four straight lines, connect the nine dots together without raising your pencil from the page. How can you connect nine dots without raising a pen from the page? Give it a go right now, and then scroll down the page to get the answer. Each line must begin exactly where the previous line ended. Make a mark with your pencil anywhere on the paper and draw four straight lines without lifting your pencil from the page. You may practise this right now by rapidly drawing nine dots on a sheet of paper and then trying to solve the problem with a pencil. How can you solve the nine dots problem while keeping all of this in mind? The objective of the problem is to connect all nine dots with four straight lines or less, without raising the pen or sketching the same line more than once. Alternatively, fold the paper three times so that the rows of dots all line up, and then fold it again to allow the pencil to pass through!Īlso, do you know what the 9-dot puzzle is? ![]() Your goal is to connect all nine dots with just four (or less) straight lines, without taking your pencil from the page and without retracing the lines you have already drawn. Is it possible to connect all nine dots with four straight lines without lifting your pencil from the page in this situation? ![]()
