Working with areas Areas appear on the palette as a control point within a shaded box, and they can be used to fill in any region regardless of its shape. Wherever you place the point on the graph, the filled-in region will extend beyond that point until it reaches another graphical object or the edge of the graph. Suppose the following graph represents a painting on a canvas. Use the black point (plus symbol) to draw the line bisecting the barn door, then use the purple area (diamond symbol) to shade the barn door. Afterward, use the tan area (rectangle symbol) to shade the roof of the barn and the blue area (circle symbol) to shade the sky. Note: You will not be graded on any changes you make to the graph. ? Door divider Barn doors CANVAS HEIGHT (Inches) Root Sky CANVAS WIDTH (Inches) More about areas Selecting anywhere in the shaded region other than the control point will sometimes reveal the area of the shaded region. As with other tool tips, it will not take the graph axes' units into account. Areas are graded based on the shape of the entire filled-in area, not on the specific location of the polnt defining the area. (There will often be multiple correct placements for the point defining the area.) square By selecting the filled-in regions on the graph, you can determine that the area of the canvas covered by the barn door is equal to Inches. Which of the following statements are true regarding areas? Check all that apply. Changing the position of other objects on the graph may change the shape of the possible regions you may fill. Areas can be used to shade a region of any shape. You are graded on the precise location of the point used for the area object, not the filled area it generates. Working with polygons Once you have placed a polygon on the graph, you can adjust its shape by selecting and dragging any of the polygon's endpoints to another snap polnt. As with lines and curves, you can also select the entire polygon to change its location on the graph without changing its shape. In some cases, you can view the area and perimeter by selecting anywhere within the polygon other than the endpoints. Use the purple rectangle (diamond symbols) to again shade the barn doors, then use the tan triangle (rectangle symbols) to shade the roof.
