2.1 transformations

1. identify the transformations shown in the following graphs and write the names of the transformations in the corresponding boxes under each graph.
2. consider $overline{ab}$ in the coordinate plane below. the dashed line segments represent transformations of $overline{ab}$.

describe each of the following line - segments as a result of a transformation of $overline{ab}$
describe the transformation
$overline{cd}$
$overline{ef}$
$overline{gh}$
$overline{mn}$

Explanation:

Step1: Recall transformation types

In geometry, common transformations are translation (slide), reflection (flip), rotation (turn).

Step2: Analyze first - set of graphs

For the first - set of graphs (top part):

• If a figure moves from one position to another without rotation or reflection, it is a translation. If it is flipped over a line, it is a reflection. If it is turned around a point, it is a rotation.

Step3: Analyze second - part (line - segment transformations)

For the line - segment $\overline{AB}$ and its transformed versions $\overline{CD},\overline{EF},\overline{GH},\overline{MN}$:

• Check the direction and distance of movement. If the line - segment moves horizontally or vertically or both without changing its orientation, it is a translation. If it is flipped over a vertical or horizontal line (or any line), it is a reflection. If it changes its orientation around a point, it is a rotation.

Answer:

(Without seeing the actual graphs clearly, we can't give specific answers. But for the first part, possible answers for each graph could be 'Translation', 'Reflection', 'Rotation', 'Translation' (assuming different types for each graph). For the second part:

• $\overline{CD}$: If it is moved up or down or left - right without flipping or turning, it could be 'Translation'.
• $\overline{EF}$: Similar analysis, could be 'Translation' if it just moves.
• $\overline{GH}$: Could be 'Reflection' if it is flipped over a line.
• $\overline{MN}$: Could be 'Rotation' if it is turned around a point.)

Please note that a more accurate answer would require a clear view of the exact positions and orientations of the figures and line - segments in the graphs.
