1D figures are important in the real world because if we did not have 1D figures, the we wouldn't be able to make 2D and 3D figures.

A geometric figure is a shape like a square or rectangle and it can be used in different views like 3D, 2D and 1D would be just a line. So there is your answer!

A 3D shape stands for Three-Dimensional. The three dimensions are Height, Width and Depth. A line just has height, so it is 1D. A polygon has both Height and width so it's 2D. A three dimensional object has all three; Height, Width and Depth.________^Height/Length = 1D-------------------| || | Depth |/ |----------------- |

2d+1d= 3d

It doesn't have any volume (3D) and it's not a line (1D). Thus, it is a 2D shape.

3d-3d cancel 2d-3d=-1d 8=-1d-17 -17+17 cancel 8+17=25 25=-1d 25/-1=-1d/-1 d=-25

3d + 8 = 2d - 7 3d -2d = -8 - 7 1d = - 15 d = -15

The letters means the direction to move (l:Left,r:Right,u:Up,d:Down) and the digits are the count of moves you have to do (i.e. 3d means 3 moves down) 1l 3d 5l 1d 1l 1u 1l 1u 1r 1d 6r 1u 2r 3d 1l 1d 1u 2r 1d 1l 4u 3l 1d 6l 1d 1l 3d 1l 2d 1r 1u 7r 4u 1l 1u 4l 4u 4r 1d 2r 3d 5l 1d 3l 3d 1l 2d 1r 1u 10r 5u 1r 1u 2l 1r 6d 3l 5u 1r 2u 2d 5l 1d 2l 2u 1r 3u 4r 1d 2r 1u 2r 1d 4l 1d 1l 1u 3r 3d 1l 3d 2r 2l 2d 3r 5u 1r 1u 2l 1r 4d 3l 3u 1r 2u 2d 5l 1d 2l 2u 1r 3u 2r 1d 2r 1u 2l 2r 1d 2r 1u 2r 1d 4l 1u 2l 1d 1r 1u 1r 1d 2r 3d 1l 5d 2r 1u 1d 2l 2u 2r 1d 1r 4u 1r 1u 2l 1r 4d 3l 3u 1r 2u 2d 5l 1d 2l 2u 1r 3u 2r 1d 2r 1u 2l 2r 1d 2r 1u 2r 1d 4l 1u 1l 1d 3r 2d 2r 6d 3r 5u 2l 2r 5d 3l 5u 1r 1u 2l 1r 4d 3l 3u 1r 2u 2d 5l 1d 2l 2u 1r 3u 2r 1d 4r 3d 5l 1d 1l (2u) 2d 2l 3d 1l 2d 1r 1u 2r 2u 1r 2u 1l 1u 4r 4l 1d 3l 2u 1l 1d 1l 1d 5r 1u 1r 1d 3l 3d 1l 2d 1r 4u 3d 7r 4u 1l 1u 5l 1d 2l 1u 2l 1d 4r 1l 4d 2r 1u 1l 1d 1l 3u 3d 10r 6u 2l 2u 4l 1u 2l 3d 1l 2d 2l 2r 4d 7r 4u 1l 1u 3l 1d 1l 1u 4r 1d 1r 4d 7l 4u 1r 2l 1u 2l 1d 3r 4d 10r 6u 2l 2u 2l 1u 1l 1r 1d 2r 1u 2r 1d 5l 3r 3d 6l 5r 5d 3l 2u 1r 1u 1r 1l 1d 1l 2d 3r 4u 2d 3r 4u 2l 1d 5l 3r 2d 1l 1d 2l Gerald
