investigate transformations
- social studies nautical flags are used by ships for signaling. flipping a flag vertically can be a sign of distress. the flag representing the number 7 is shown. where is the yellow side if the flag is flipped vertically? explain.
- a quadrilateral has a pair of vertical parallel sides on the left and right of the figure. ryan turns the quadrilateral one - half turn clockwise. where are the parallel lines on the turned figure?
- does each pair of shapes show a flip, slide, or turn? if so, identify which.
a. two trapezoid - like shapes
b. two quadrilateral shapes
- attend to precision complete the drawing of the shape slid to the right. two pentagons, one incomplete
- stem a biologist is studying leaves with line symmetry. complete the biologist’s sketch of the leaf by flipping the shape across the vertical line. a zig - zag triangle shape with vertical dashed line
- attend to precision complete the drawing of the shape after it has been turned. a square and a partial shape
Question 1
The flag is a triangle - like shape with yellow on top and red at the bottom. A vertical flip (reflection over a vertical line) will reverse the vertical orientation. So the yellow side, which was on the top, will now be on the bottom (or we can think in terms of the position relative to the flag's axis; after flipping vertically, the part that was above the axis is now below and vice - versa).
A one - half turn (180 - degree rotation) of a quadrilateral with vertical parallel sides (left and right) will make the left and right sides become horizontal. Because a 180 - degree rotation changes the orientation of the sides. If the original sides were vertical (parallel to the y - axis), after a 180 - degree rotation, they will be parallel to the x - axis (horizontal), and they will be the top and bottom sides of the rotated quadrilateral.
The two shapes are mirror images of each other across a vertical (or some) line. A flip (reflection) is a transformation that produces a mirror image. So this pair of shapes shows a flip.

After flipping the flag vertically, the yellow side will be at the bottom (or the lower part of the flag). The vertical flip is a reflection, and it swaps the top and bottom (in terms of the vertical position of the yellow region) of the flag.
