To connect 4 dots with 3 lines, you can use a geometric technique called a "triangle paradox." Start by drawing a triangle connecting three of the dots. Then, draw a line from the remaining dot to the midpoint of one of the triangle's sides. Finally, draw a line connecting the midpoint of another side of the triangle to the remaining dot. This will create a figure that connects all 4 dots with only 3 lines.
This question is not complete. The correct scenario begins with 4 dots arranged in a square. The challenge is as follows: # Draw three straight line. # You cannot lift your pencil. # You can not cross over any lines. # You must end on the same dot you start with. The solution is to simply think outside the box. Draw a large triangle. Start with your pencil on a single dot (We'll use the bottom left for this example). Draw a straight line to the right that extends past the dot on the bottom right. Then draw from that point diagonally towards the top left, going through the dot at the top right, and ending directly above the two left dots. Finally draw a line straight down, going through the top left and ending at the bottom right.
Go outside the box. The 45 degree angles pick up the dots below the corners, but you have to extend the other lines beyond the figure formed by the dots.
Put the dots in a general square outline. But make one side have 4 dots and the others have 3. Then go around the outline of the square.

a star drawn with five lines will give you 10 dots on 5 lines with only 4 dots on each line. (or) simply draw a pentagon and put a cap ( a inverted 'V') on all sides.

You start by drawing a circle then draw 3+ dots on the circled edge, next connect all the dots with each other but don't go over the same line twice. for a 4 dotted circle you should end up with 6 lines altogether and with 5 you should have 10 lines altogether also 6-15 7=21 10=45 11=55 12=66
Write down 4 rows of 3 dots or 3 rows of 4 dots.
If this is the one where the dots are in a square 3 x 3, and every dot must be connected by a straight line to every other dot, I do not think it can be done.

= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.
