Study Notes
Transformations Overview
- Vertical stretches alter the shape of figures, impacting area and side lengths.
- Transformations can change the spatial properties of geometric figures.
Rotations
- A square's vertex can be rotated 270° clockwise about the origin, moving vertex E' to Quadrant III.
- The center of rotation is identified as Point X.
- A standard rotation angle is often expressed as 90 degrees.
Reflections
- The line of reflection can be designated by the x-axis, which serves as a mirror for geometric transformations.
- Reflecting point A at coordinates (-2,4) results in point A' at (-2,-4).
Composite Transformations
- Mapping hexagon 1 to hexagon 3 involves reflections across both the y-axis and x-axis.
- For triangle LMN, a reflection over the line y = x followed by a translation leftward by one unit results in side N'L' touching the y-axis.
Image Analysis Post-Transformations
- After performing a reflection over the x-axis and translating one unit left, point N' is positioned at (-2, -1).
Diagram-Based Transformations
- Triangles can be categorized by their transformations:
- Translation is observed in blue and red triangles.
- Rotation is represented by two small purple triangles.
- Reflection can be seen with two large blue triangles.
Special Cases of Transformations
- When analyzing transformations of a square with vertices Q(0,0), U(0,4), A(4,4), and D(4,0), an isometric transformation yielding new vertices Q'(0,0), U'(4,0), A'(4,-4), and D'(0,-4) indicates the process involved a rotation.
