Based on the analysis of the worksheet "Drawing Reflected Shapes," here is a comprehensive solution and explanation for each problem.
The core principle for solving all these problems is
geometric reflection. To reflect a shape over a mirror line, you must create a mirror image of the shape on the opposite side of the line. Every point on the original shape must be the same distance from the mirror line as its corresponding point on the reflected shape, but on the other side.
Here is how to solve each problem:
1.
Problem 1 (Vertical Mirror Line): The diamond shape is to the left of a vertical mirror line. To reflect it, you would draw an identical diamond to the right of the line. For each vertex of the original diamond, measure its horizontal distance to the mirror line and plot a new vertex the same distance away on the right side.
2.
Problem 2 (Horizontal Mirror Line): The castle-like shape is above a horizontal mirror line. To reflect it, you would draw an identical shape below the line. For each vertex of the original shape, measure its vertical distance to the mirror line and plot a new vertex the same distance away below the line.
3.
Problem 3 (Horizontal Mirror Line): The checkmark is above a horizontal mirror line. Reflect it by drawing an inverted checkmark below the line, ensuring each point is mirrored vertically across the line.
4.
Problem 4 (Horizontal Mirror Line): The bone-shaped object is below a horizontal mirror line. Reflect it by drawing an identical bone shape above the line, mirroring each point vertically.
5.
Problem 5 (Horizontal Mirror Line): The wavy, zig-zag shape is above a horizontal mirror line. Reflect it by drawing an inverted version of the wave below the line, with each peak becoming a trough and vice versa, all at equal vertical distances from the mirror line.
6.
Problem 6 (Vertical Mirror Line): The X-shape is to the left of a vertical mirror line. Reflect it by drawing an identical X-shape to the right of the line, mirroring each point horizontally.
7.
Problem 7 (Vertical Mirror Line): The S-shape is to the left of a vertical mirror line. Reflect it by drawing a backward S-shape (or a mirrored S) to the right of the line, ensuring each point is mirrored horizontally.
8.
Problem 8 (Horizontal Mirror Line): The shape with a scalloped bottom is above a horizontal mirror line. Reflect it by drawing an identical shape below the line, with the scalloped edge now pointing upwards.
9.
Problem 9 (Horizontal Mirror Line): The complex shape is above a horizontal mirror line. Reflect it by drawing an inverted version of the entire shape below the line, mirroring each vertex and edge vertically.
In summary, to complete this worksheet, you must carefully trace each shape's vertices and edges, calculate their distance to the given mirror line (horizontal or vertical), and then plot the corresponding points on the opposite side of the line at the same distance. Connecting these new points will give you the correct reflected shape.
