Not necessarily. The horizontal and diagonal lines are also straight lines.
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
Lines have no end (stretch on forever) Line segments start and end.
A polygon is a generic term describing a closed plane figure bounded by 3 or more straight line segments. It need not have any perpendicular lines.
Including its diagonals there are 6 perpendicular lines
Two lines or segments that form a right angle are said to be perpendicular.
A perpendicular diagonal is a pair of segments or lines that cross a polygon making a perpendicular
Line segments, perpendicular lines, and intersecting lines.
Two lines or segments that form a right angle are said to be perpendicular.
The segments of a square are perpendicular. Take the letter " T " for example. Where the bottom line connects the the top line forms a 90 degree angle, which makes them two lines perpendicular.
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
A plus sign (+) would be a pair of perpendicular line segments.
Each of the eight line segments is perpendicular to 2 line segments. So there are 8 pair in all.
