The task involves completing the symmetrical shapes by drawing the missing half of each shape. Symmetry means that one side of the shape is a mirror image of the other side with respect to a given line (the dashed line in this case).
Steps to Solve:
1.
Identify the Line of Symmetry: The dashed line in each shape represents the line of symmetry. This is the axis along which the shape should be mirrored.
2.
Mirror Each Shape: For each shape, reflect the given part across the dashed line to complete the symmetrical shape.
Solution for Each Shape:
#### 1.
First Row:
-
Shape 1: A rectangle with one side and a corner visible.
-
Action: Draw the opposite side of the rectangle to complete it.
-
Shape 2: A curved shape with one side visible.
-
Action: Mirror the curve on the other side of the dashed line.
-
Shape 3: A triangle with one side visible.
-
Action: Complete the triangle by drawing the other two sides symmetrically.
#### 2.
Second Row:
-
Shape 4: A semicircle with one side visible.
-
Action: Draw the other semicircle to form a full circle.
-
Shape 5: A trapezoid with one side visible.
-
Action: Reflect the visible side to complete the trapezoid.
-
Shape 6: An isosceles triangle with one side visible.
-
Action: Complete the triangle by mirroring the visible side.
#### 3.
Third Row:
-
Shape 7: A rectangle with one side visible.
-
Action: Draw the opposite side to complete the rectangle.
Final Completed Shapes:
Here are the completed shapes based on the above steps:
1.
First Row:
- Rectangle
- Curved shape (mirrored)
- Triangle
2.
Second Row:
- Circle
- Trapezoid
- Isosceles triangle
3.
Third Row:
- Rectangle
Explanation:
-
Symmetry means that if you fold the paper along the dashed line, the two halves should match perfectly.
- To draw the missing half, imagine reflecting the given part across the dashed line as if using a mirror.
Final Answer:
\[
\boxed{
\text{Draw the missing halves as described above to complete each symmetrical shape.}
}
\]
