Geometric Lines with Examples and Pictures

Straight

A straight line is a line that extends infinitely in both directions and does not curve or bend.

Example: The ruler drew a straight line from one end of the paper to the other.

StraightPin

Diagonal

A diagonal line is a line that slants or slopes at an angle, connecting two nonadjacent corners or points on a surface.

Example: The road cuts diagonally across the field, making a shorter path to the other side.

DiagonalPin

Vertical

A vertical line is a straight line that runs from top to bottom or bottom to top, perpendicular to the horizontal plane.

Example: The flagpole stood tall and straight, with a vertical line running from the ground to the top of the flag.

VerticalPin

Parallel lines

Parallel lines are two or more lines that never intersect or meet, no matter how far they are extended in either direction.

Example: The train tracks run parallel to each other, creating a straight path for the train to travel on.

Parallel linesPin

Curved

A curved line is a line that changes direction gradually, creating a smooth and flowing shape.

Example: The roller coaster track was full of curved lines and loops, making for an exciting ride.

Horizontal

A horizontal line is a straight line that runs from left to right or right to left, perpendicular to the vertical plane.

Example: The horizon appeared as a straight, horizontal line where the sky met the sea.

HorizontalPin

Dotted

A dotted line is a line made up of a series of dots, with small gaps in between each dot.

Example: The dotted line on the map showed the route of the hiking trail through the forest.

DottedPin

Wavy

A wavy line is a line that moves in smooth curves and bends.

Example: The river flowed in a wavy line through the valley, creating a beautiful and natural landscape.

WavyPin

Zigzag

A zigzag line is a line that moves back and forth in a sharp, angled pattern, resembling the letter “Z”.

Example: The lightning bolt left a zigzag line in the sky as it flashed through the storm clouds.
