7 horizontal lines and 10 vertical lines how many rectangles?
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.
Oh, dude, let me count... Okay, so in a 5 by 6 grid, you've got like 15 horizontal rectangles and 10 vertical rectangles, but don't forget the big one that covers the whole grid, so that's like 26 rectangles total. So, like, yeah, there you go.
