It depends on how spaced apart all the lines are.
7 horizontal lines and 10 vertical lines how many rectangles?
In a 3x3 grid, you can form rectangles by choosing two horizontal and two vertical lines. A 3x3 grid has 4 horizontal lines and 4 vertical lines. The number of ways to choose 2 lines from 4 is given by the combination formula ( C(4, 2) ), which equals 6. Therefore, the total number of rectangles is ( 6 \times 6 = 36 ).
NONSENSE
there are four two vertical two horizontal
two: horizontal and vertical
In a 4 by 4 grid, there are 16 squares (1x1 squares), 9 rectangles that are 2x1, 6 rectangles that are 3x1, 4 rectangles that are 2x2, and 1 rectangle that is 4x4. Therefore, in total, there are 16 squares and 20 rectangles in a 4 by 4 grid.
The number 8 has only 2 lines of symmetry; Vertical and Horizontal.
Two lines of symmetry; one vertical and one horizontal
16 * 28 = 448
The slope of a vertical line is undefined. The slope of a horizontal line is 0. Hope this helps.
Oh, dude, like, there are 10 rectangles in a 4 by 4 square. You got your big rectangle, then you got 4 rectangles that are 3 by 2, and then you got 5 little 1 by 1 squares. So, yeah, that's like 10 rectangles in total.
Yes, but only if they are exactly vertical and exactly horizontal (90 degrees angular difference). For real-world examples, many vertical lines can be perpendicular to a single "horizontal" curved line at the points of intersection.
