How about Z, E or F
Z
The letter "D" has only one line of symmetry, going horizontal across the letter.
Horizontal only
In general, they are called horizontal lines, but they will only be that if they have a zero slope. They'll be "level" or "flat" lines.
Only 1: it's horizontal, along the middle.
Z
The letter "D" has only one line of symmetry, going horizontal across the letter.
Because they only go in one (1) direction.
Only longitutude crosses latitudinal lines (horizontal circles)
The number 8 has only 2 lines of symmetry; Vertical and Horizontal.
Horizontal only
In general, they are called horizontal lines, but they will only be that if they have a zero slope. They'll be "level" or "flat" lines.
Yes, you've got the right idea, but they're only horizontal if you're holding your map the right way.
Only 1: it's horizontal, along the middle.
You need to visit a physician to have lines on your toenails checked. This could be a sign of serious conditions that only a doctor can diagnose.
The letter "M" has 5 sides if you consider each angle and line segment. It consists of two vertical lines, two diagonal lines that meet at a point, and a horizontal line connecting the bottom of the verticals. If counting only the straight edges, it can be described as having 4 distinct segments.
No, there is only 1 set of parallel lines in the letter M.
