Homework #$2$

Workbook Problems:

$3\mathrm{.}1$ Ridge Gasket: Sketch the ridge gasket using the rectangular grid.

$3\mathrm{.}3$ Coordinates $1$: Four grid lines equal to one unit. In the upper half of the rectangular

grid paper, sketch the figure using the following absolute coordinate values: $0,0$;$3,0$;

$3,2$;$0,2$; and $0,0.$ In the lower half of the rectangular grid paper, sketch the figure

using the following relative coordinate values: $0,0$;$4,0$;$0,3$;$-4,0$; and $0,-3.$

$3\mathrm{.}4$ Coordinates $2$: Four grid lines equal to one unit. Using the isometric grid paper and

following the right$-$hand rule, place and label points at the following locations: $0,0,0$;

$4,0,0$;$4,2,0$;$0,2,0$;$0,0,2$;$4,0,2$;$4,2,2$; and $0,2,2.$

After placing the points on the isometric grid, connect the following points with lines:

$1-2,2-3,3-4,4-1,5-6,6-7,7-8,8-5,4-8,3-7,1-5,2-6.$
